It's still a useless project, but I continued on, like a fool. Tweaked performance, colors, layouts, and fonts, and I think it's readable enough at any resolution (with scaling in OBS).
Also fixed a bug pertaining to grabbing the viewer image to use as the cube texture.
I say I'm done with it, but I know I'll go back to it.
Probably the most pointless thing ever, but I write a lot of pointless things, so maybe I've written something more pointless along the way. Maybe not. (Yes, it grabs the chatter's user pic from justin.tv and uses it on the cube)
