Nope, not a scam.
Notice our wiki:
http://opentransactions.org -- we haven't started using any logos yet because we're waiting until the artists are paid.
da2ce7 is responsible for 2 BTC, I am pitching in .6, and marcus is coming up with the other 1.4
Since the price of BTC has dropped, I will also pay some extra to the artists. (Anyone want to sell me some BTC for paypal?)
Sorry about delay, I've been traveling for the past 2 weeks.
