Paper: Is there anything it can't do?

My RSS Aggregator is just full of papercraft ideas thanks to a certain magazine, so if you don't mind I'm going to dump them all in here at once.  Ready?

Gardening:

• My wife likes  buying those little plastic trays to help seedlings grow, but perhaps this pot made out of newspaper would be a more eco-friendly way to do it.
• Of course I tend to kill any plant I touch.  Perhaps it would be better if I just made one of these papercraft models of houseplants instead.

• I like to snap pictures of exemplary student work, but if it's 3D I sometimes run into the problem of having a distracting background and/or difficult to control light sources.  Next time, I might just build a papercraft macro studio!  (They say it's an origami studio, but I was always told traditional origami has to start with 1 square paper.  This design doesn't have t o start with a square to work well.)

• My wallet that's made out of duct tape is holding up quite well, but when it's eventually worn out I might go with this simple paper wallet instead.  3 cuts and a bunch of folds is all you need!  (And it's not as sticky as a wallet made out of tape, either.)

• Do you remember back when Mario didn't have to go everywhere with a cast of about 50 of his closest friends?  Bring back the days of the first Super Mario Bros. game with these two papercraft models!  (World 1-1 & World 1-1 End)
