Welp, I decided to move on from shaders for now after bonking my head on the keyboard a lot this morning. Now I want to make some sort of cute little live wallpaper with 3d models! Since I'm most comfortable with GDX, I decided that I'll be using it. I'm also going back to using my custom preference screen, because I have much more control over it (even if it does take a bit more work to configure)
Anyways, I'm excited. I've made my own 3d models in the past and I'm looking forward to making some more. There's a buncha little blocky guys in the near future!
