Today I folded

a dinosaur for a three year old...
I was at lunch with a lot of people today, and mentioned to the person on my right that I was teaching folding --- and he seemed surprised and impressed when I said I had created a dinosaur fold. I tried to play it down, pointing out that it builds on other people building on other peoples designs, but still he was impressed.
So I whipped out a sheet of paper, tore a square, and folded there and then. The table gradually started looking until all eyes were on my hands. And the finished beast was passed around the table from hand to hand until everyone had had a chance to oooohhhh and aaaahhhhh over it.

Yours, vainly trying for modesty,
