The idea here came from looking at a series of bars on a graph, thinking they looked a bit like a game of Tetris, and wondering if I could make that work. For the most part, I think I succeeded and this cartoon turned out well. But with a little time and distance, I look at it now and think, "You know, if he doesn't turn it, sales would rise sooner, but then plateau for a while. Is that better? Would leaving that space underneath be bad somehow? And if he did turn it and drop it, would that bottom row disappear?" Maybe it's best not to over think this one.
