Basswood: I first bought it as it comes in a 1/4" plank from the hobby wood stand at Hobby Lobby. I suspect that your local hobby shop would have the same. I can't speak to any characteristics vs. pine other than that it has no discernable grain and drills just fine.
Avatar: It's likely that you took your picture with the camera turned, and for whatever reason that info isn't making it to the avatar picture. Load it onto your computer and save it there, and it should put the (0,0) { <- that's zero comma zero, not an owl} in the right place. Or load to Photobucket; if it appears to lay on the wrong side, you can rotate the pic and save it, then use it for the Avatar.
