His name is Marek and he appears to be dabbling heavily in truespace and other programs.

I did find tutorials and something called:
Caligari Parser Project
I added him to this game development section because that seems to be his primary aim, and he also has his own file extension (.vmk) which he appears to have created for his needs.
Lots to see on his site.
The viewer works great for trueapce files as well.
