This is who I am, no way not to get carried away by each and all the shiny baubles I stumble upon. Which means after only a taste of this, papercraft (the VF I mentioned before) I downloaded tons of models for other proyects, even if it's not likely I'll ever try a tenth of them. The best ones (Stars Wars, Star Trek, Back to the Future) I took from Taringa: here, here and here, but there are other interesting places to check:
Paper Inside, still not that big, but great quality. Took Harry's wand from it, and Kenny.
Yamaha Paper Crafts, ultrarealistic Yamaha motorbikes (and rare animals).
Canon Creative Park, colourful.
3D paper models, confusing, but apparently huge.
Just wish I'd found Spike's Swordfish II - that, I would have *loved* to make, even more than the gundams (which are a must in any self-respecting wish list).
