There's Always a Better Way...

For me, one of the constant delights of engineering is that any design, no matter how good it is, can be improved.  Even seemingly simple things can always be made better.  The world of software (where these days I do nearly all of my engineering) is perhaps an extreme case of perfectability – it's hard to even imagine a piece of software that couldn't be improved in some way.

Here's an example that delighted me: a better way to fold a piece of paper.  It's much harder to explain than to actually do it – if you follow the instructions linked on that site, you'll see that it's not hard at all.  Awesome!
