This idea might not have changed my life, but it changed my day :-) (Within seconds and for the better; what more could you ask for?)

This makes me think of a story I like:

Somewhere in the ocean is a place called the "Dragon Gate". Any fish that swims through the Dragon Gate turns into a dragon. However the Dragon Gate is invisible. Also, when a fish swims through it the fish doesn't look any different afterwards. And finally, after a fish has swum through the gate it doesn't feel any different, it just is a dragon.

Great quote! - "Programmers are still stuck writing their incantations down in a way that devices made of elaborately etched metalloids — powered by lightning energy gained from harnessing the power of the wind, water, or, most commonly, motion itself via the liquified corpses of ancient beasts that used to dominate the earth — can understand and execute."
