Grow Crowd Icon is a fun project done several months ago. They ask me not to publish until the app is ready. Now, they seem preparing for the launch in near future... be the first to know! Get notified now! Thanks
Your buddy has great art, don't get me wrong. If you want to help support him, put things up about him in your own profile and submitted pieces. That's great. But it is rude of you to advertise another's work on someones else's art piece.
