Sometimes something can be so simple, yet amazingly beautiful.
This is the Electronic Butterfly In A Jar from ThinkGeek.
It's a butterfly. In a jar. That you can watch and enjoy and won't die. You don't have to trap it and you don't have to feed it and you get to feel like a little kid all at the same time.
It's also only 20 bucks and come in 4 different butterfly varieties.
Geek. Girl. Joy.
