Check out ripplesketches.blogspot.com if you want to make a donation to help the animal victims of the Deep Water Horizon Gulf Oil Spill, and pick up some cool art in the process.
I actually made a few quick'n'dirty ones myself. They've already been purchased (by total strangers, which is exciting!), but you can see them here, if you want.
As noted, until the end of September, I'll be donating to IMMS the proceeds of all greeting card sales from my seascape series as well as 75% of all other net sales until the end of September!
