I build that one too (not my first papertoy though)
Lelouche Lamprouge by Chris Beaumont of Cubeecraft. Saw it on adult swim. http://www.bumpworthy.com/bumps/1564
my first papertoy was hellboy by hamhead or something. :P
I made St30's fish papercraft at his house. The amount of papercrafts in his room is astonishing to say the least. I just designed my first model, it's on the front page. I think it's an udder masterpiece.
My first paper toy was a Dr Who Tardis of my own design made out of thin red card and sellotape. It must have been about 4cm tall. I was only 8 at the time. Many years later after a lifetime of origami, point of sale design and fascination with paper in general, I discovered Toy-A-Day and I was hooked.
