This is pretty cool.
A friend of mine shared it on facebook as a "HEYYY you can play this stuff while you're reading!" thing. And I clicked it, and being the loyal NarniaMUCKer I am, I immediately went, "HEYYY you can play this stuff while you're RPing!" And I did. And it was fabulous. There's a bunch of great nature-ish noises that are fantastic for building ICly-relevant soundscapes, so that was entertaining.
And also. Darth Vader. Yes.
I, uh, might have spent more time fiddling with the different noises and volumes and frequencies than I did posing in that particular RP. DO AS I SAY NOT AS I DO, KIDS.
