As has been, uh, kindly suggested , April's art challenge will be a Trek homage to Arthur C. Clarke. I don't know what kind of influence each had on the other, but they've certainly both had an effect on sci-fi in general. Whatever you want to do with it is fine by me, as long as you can relate it to the topic! In case some of you aren't familiar with some of Clarke's other contributions, might I start you off at the wikipedia page? He's done a lot more than just write science fiction!
