These are two of the three blocks from the thwomp fan game that I will post to YoYoGames soon.  These two have a gradient that was hand pixeled.  I didn't want to hand pixel the gradient for the larger box so I used the photoshop gradient tool.  I forgot when I submitted originally.  But each of these were pixeled per pixel by me.  Each platform has 10 colors so the larger platform's gradient isn't as smooth
