Stuff I absolutely do not need but if I was rich you better fucking believe they'd be in my possession:
LED Faucet from thinkgeek.
This is $14, so you don't have to be THAT rich to justify that purchase (although you still need SOME amount of extra spending money to be worth it). I want one too, and idk maybe if I had $250 of pure spending money I could see it.
See now something else they had on freshome (which I saw when I saw that faucet also) were thermal tiles for showers that changed colors with temperature, but the tiles were $17 each. So, a whole shower would cost quite a lot. Still, it would totally be in my dream home.
edit: oh the faucet is $20 for the red AND blue, that's the only one that's worth getting imo
My problem is that if I had that spending money there are too many other things I'd get before that faucet.
