Hey. So, here's another version of my BlendSling launcher. This one uses Blender 2.66a's BlenderPlayer. I've also uploaded an OS X version. As a side-note, the Linux versions were created on Windows, so they may or may not work. Feel free to give 'em a tug and see if they fall apart.
For more information on what BlendSling is, you can check out the previous post here.
Apparently, to browse a folder you need a Box account, so here are links to the individual files.
