As some of you know, pitch/yaw was broken in 3D Box since version 0.99.
I attempted to fix it, and it seems to work. So please give it a shot:
It also has a new icon, which is a blatant use of a .psd by thedevstudio.deviantart.com
Here's David's skybox demo, slightly tweaked to accomodate 0.99 changes:
Skybox2.zip (careful, huge textures, almost 2Mb)
Mind you, the pitch/yaw bug is the only one I fixed. In fact, I only changed one file, Drawing.cpp. Here's my version: Drawing.zip
