I came across this post on Swissmiss about a company called Nutcase Helmets (their website seems a little hit or miss for actually coming up) that makes really cool looking hard shell bike helmets. And with a name like Nutcase, and making hard shelled bike helmets, an idea occurred to me for a bike helmet that I think would be really funny (your sense of humor may vary).
I’d like to see a bike helmet that looks like a giant walnut shell. You could even make it the sporty kind with vents to have the bumpy texture of an actual walnut shell, and the rounded front and slightly tapered back would be the right shape too. And then you could look like when a cartoon mouse is riding a motorcycle or a race car and they have buttons for wheels, and match sticks for handle bars, and a walnut shell for a helmet. For that matter, you could make a whole custom bike to go with the helmet so it would look like the whole thing was made out of over-sized tiny things – button wheels, match stick handle bars, a walnut helmet, a pleasantly ironic hamster wheel for the gears, toothpick pipes, a thumb tack seat (pointy part down!!), clothespin brakes, the whole deal. Insert your own gag about joining / leaving the rat race here. In short:
Do the math.
