Jan Rukr is the creator of the M-41 Pulse Rifle papercraft I'm building.
Right now, he is in the finishing stages of his latest creation (which he will release to the world when all the bugs are ironed out).
Yes, it's the Sulaco - the Colonial Marines starship from Aliens.
This is Jan's desk in his apartment. What you can see of the Sulaco is about one third of its final complete size, which is about 1.6 *metres* long.
