Nguyen La Chanh's ingenious design is made from a decay-free foam called plastazote, and populated with three varieties of moss: ball, island, and forest. Maintenance required for this little patch of green is limited, as the moss thrives off of the humidity released from daily bathroom rituals.
I want one. I just question how much traffic the mat can stand. Granted, that wouldn't be a problem for me -- I only shower bi-weekly. It's called cologne, folks, and I'm saving the planet one less shower at a time.
Hit the jump for a couple more pictures.
Thanks to Melissa, who doesn't need a bathmat because she's an elf princess and only bathes in the sacred fountain of beauty, which has naturally moss-lined banks.
