3D file viewer. Nice GUI but I had a problem - from time I started the program it was like it was redrawing 1 fps. Even before I loaded a 3D model it was slow, seems that it has some kind of bug, which is making it work slow on my PC. When I loaded Collada models I saw that they were rendered nicely, but it can load only basic collada models, not models with skinning or node transforms.
