Had a good time with this one - wasn't sure how to approach it at first, so I just started with the background, then tinkered around with the send/receive message blocks. I'd like to go back later and fine tune this - the goal would be to not have the flower double so much. The flower was made with TurtleArt and then combined with the fist in Inkscape - it's my "constructionista" logo.
