Most awesome cat bed ever...!
This companion cube was made from the coordinates from the source files in the game. I assumed Valve used inches as their units, but this ended up a little larger than I expected, so I'm a little unsure if I made the right assumptions about units. There are almost 400 separate pieces in the cube, and all have been backed with craftfuse. It took me over a year off and on to finally finish this project.
Edit: There's been a lot of talk about my cube and how I made it. So I made a tutorial. It's in three parts on my blog:[link][link][link]
