I'm game for a good cause, and red cross blood donation and disaster relief efforts certainly qualify.  wolfpuptk has set up a raffle you guys can see here:

There's a link there to the red cross's website where you can donate money, and then you can forward on the email receipt for tickets in the raffle to potentially win art from any number of contributing artists. Check it out!
