Sparkle is a virtual worlds (VW) client for the iPhone that allows the user to login and communicate via instant messages with friends, and via proximity chat with avatars that are in the same location. Sorry, you probably need to try a VW like Second Life to understand what that’s about and why it is an exciting development. For now, please just accept that being able to connect to Second Life and interact live with others there even when you can’t log in normally is a big deal. For instance, I’ll be able to attend meetings from my iPhone and see what is being said in chat even if I don’t have my computer set up or if I’m in an internet café without my laptop.

Besides Second Life, Sparkle will connect to other grids as well, such as OSGrid or Second Life’s beta grid. Right now, those three are the only VWs available, but I’m sure others will be added as demand warrants. It’s possible to set up any number of accounts for various grids, limited only by the number of avatars you have. In fact, you can even sign up for a new account via Sparkle! Select the approprite service, fill in your account username and password, and there you go.

Choose the account you want to login with from the resulting list, click the “Go!” button, and your friends list appears on the next screen, with those online indicated with highlighted stars beside their names, while offline avatars are shown with dimmed stars. To send an IM to one, you select the name, then click the “IM” button on the next screen. A window with the virtual keyboard appears, and you proceed to communicate.

It seems pretty simple, and it is easy to use, but the implications are really awesome. The only real gripe I have about it is the requirement to use WiFi, but there is probably no way around that. Second Life in particular probably needs more bandwidth than the plain old cellular signal can provide. As it is, people who have very long friends lists (like me) have reported long waits to log in. Genkii’s tech support is working on it, and in fact I’ve had better luck logging in with my main account lately, after the first few attempts when it took several long minutes.

Sparkle IM gets a high rating from me. I’ve been waiting for someone to publish an iPhone app for connecting to Second Life, and this is a good one that works. Thanks, Genkii!

Last time I wrote, I was downloading the OpenSim server software to my external hard disk via SVN. That went well, but I have to admit that the instructions for compiling and running it on MacOS 1.5 were so daunting that I deferred that until after I’d tried out the binary under WindowsXP.

It worked! I installed and ran the binary version of the open source server on WinXP, which was installed on a virtual machine running in Parallels Desktop for Mac on my early 2006 20″ Intel Core Duo iMac, and while I couldn’t do much except look around with the camera tools (since I had not configured any of the other servers — asset, inventory and avatar databases), it was quite a thrill to know that I could have my own little world running on even a laptop unconnected to the internet if I wished. (The reason I use an external disk for my virtual machines is so I can access them using my husband’s 17″ MacBook Pro or any other Mac with Parallels Desktop installed.) I logged in using a copy of the SecondLife viewer, just editing the target definition in the shortcut’s general properties window, and using the default login ID and password of “Test User” and “Password”. The target I specified in Properties, of course, was the localhost URI, http://127.0.0.1 plus the designated port, in this case “:9000″.

Other VW Developments

In an already-running OpenSim grid (OpenLife), a week or two ago I met the person who started that system, Sakai OpenLife (OL name). It was interesting chatting with him, and he gave me a tip I’ve followed up on for porting content among VWs. He said many people have had good luck with Second Inventory, an application that creates a backup on your own hard disk of objects, textures, bodyparts, etc. as long as you have full permissions for those assets. I discovered that there is a multi-avatar version available, so while it’s a bit pricey (29 Euros, vs 14 Euros for the single-avatar version), I went ahead and bought it. It does indeed work as promised, although it is a bit slow to copy a large inventory since the “folder copy” function isn’t yet enabled and items must be backed up and restored one at a time. Folder actions are promised for the next version, though.

I ran a few tests, and I was able to back up and “restore” copies of simple and linked objects from both my primary and alt accounts in SecondLife to accounts in Open Life and OS Grid. It isn’t perfect; embedded scripts don’t always make it, and when they do they must be recompiled since not all LSL functions are available in the OpenSim VWs yet, and animations also don’t seem to come across when embedded in an object. Presumably those might be uploaded and added to objects if one has the .bvh files for them, though. My coffee mugs came through with their handles and “coffee” intact and didn’t require relinking, but the “drink” animation and script aren’t there, and the little “ring” piece used for the rim of the cup wasn’t linked. I just threw away the rings since they aren’t critical, and copied the particle steam script I used in SL, recompiled it and added it to the “steam” prim, but I haven’t done anything about the animation yet.

Interestingly, once I had the backups made, I could restore inventory items from my SL alt account as well as my main account to either SecondLife or another VW with impunity. The owner’s name didn’t make any difference to the software. When an asset is “restored” to an inventory, whether it came from that account or not, the owners name becomes that of the account that it’s being restored to, not the source inventory owner’s. There is certainly some potential for mischief here, especially since I was also able to “back up” some full-permission assets that I did not create, and when they were restored my avatar’s name showed up as the creator.

Copyrights and DMCA Issues

The ability to “rebrand” items that I owned full permission copies of, but had not created, made me wonder what the attitude of some of the content creators in SecondLife were toward these brave new virtual worlds. Would I be able to legally use copies of fulll-perms textures I’d bought in SecondLife in other worlds? I sent that question to one of the texture store owners I’ve patronized extensively, LilyBeth Filth, owner of Textures-R-Us. Predictably, she said, “No.” Here’s a direct quote from her IM, which I think explains her reasoning and the problem very well:

Hi, Our User License does not allow customers to use them in any other virtual world including SL open source clients. The reason for this is because they would be uploaded in your name and not that of the creator. In time people will share these textures with friends (as they always have) and before we know it people are selling work created by the original artist but uploaded by other people and it creates a nightmare of a DMCA issue. We create & sell textures for SL only. Sorry. LillyBeth 2008/5/17

So, it sounds like there could well be a whole new round of rights issues to hash out, even when the dream of a mostly seamless metaverse becomes a reality. The technology is not the only thing that needs to be mastered.

I naturally immediately signed up for an account (katlemieux) and briefly explored this Web-based world, which only opened to the public this Monday. So far, they have two types of “rooms” available which one can rent on a daily basis and invite people to join you for free, and two generic avatars, “Joe” and “Jane”, which can be customized to a limited degree. With a Pro account, one can upload textures to create a better looking avatar and wardrobe, etc., but so far I haven’t found any specifications for those.

In general it looks promising. The idea of a low-cost, Web-accessible virtual meeting space has some real possibilities, even if it’s not visually rich yet. Already one can link to a folder of images to display as a slideshow, or a video file, and a voice chat tool is available. Adding voice to a meeting room rental (US$5.99) costs an additional fee (US$4.99), but that’s not horrible considering that people you invite to your room don’t have to pay a cent.

So far I’ve only tried browsing this site with Firefox on Mac OS X.5, but (after adding a line to my computer’s Java settings, according to Transmutable’s very clear instructions, and restarting Firefox), it worked very well. Later I’ll fire up my virtual machines with WindowsXP® and Debian GNU/Linux, and see how it works on them.

It’s really cool that the chatter in SL is being discussed in the Q&A session following Ginsu Yoon’s presentation now! How appropriate!

Avatars send questions to designated “staff” in world by instant message, who then relay them to the moderator at the conference, who asks the questions of the speaker. In this respect, the SecondLife participants are just as much a part of the Real Life conference as people in Stanford.

Obviously, these are 2D formats, not 3D. Maybe for 3D I need to look at 3DXchange2 instead? iClone is really intended for creating machinima rather than 3D models for virtual worlds, after all. The right tool for the job…
