Pretty damn cool.

right now 1btc~=$35, so i think it's a fair deal. here's what you have to do to participate:
1) you must donate to any charity of your choice. by this i mean any known, reputable organization that actually helps people (as in medical aid, education or feeding the hungry, you get the drift. no political/social movements types of orgs. please comment/msg me if in doubt.)
2) you must should send a short message to the said charity, explaining what btcs are and why they should consider accepting them as a donation. extra karma for those of you who actually succeed.
3) you must send me a verifiable receipt - i reserve the right to contact the organization you donated to before i send you any bitcoins. don't get me wrong, i believe most of you are really charming, kind, caring people, but there is no shortage of thieves and scammers, and i don't want to make their day.
4) your receipt WITH ALL YOUR PERSONAL INFO BLACKED OUT will be posted in the comments along with txid of your reward; hopefully this get enough momentum to actually make some impact in and outside of the btc community, and i don't want any idiots crying "omg is liek totaly a SCAMM!!11" and whatnot
... and that's it. let's get it going
imho there's no better way to promote bitcoins than to share some.
EDIT: Probably should have used the search function.
