Just needs some good meaning

This was simple but I liked it because I collaborated with my 3 yr old son, Toby. I drew a shape on the ipad and he continued with another shape, and so on, back and forth. Animating it produced this. This was some simple and quick to do but I like it because it has meaning to me. This tells me that, perhaps, things don't need to be complicated for it to be enjoyable. It just needs some good meaning? Just pondering here:)
