Binary Sprite Designer

This started life with me trimming out squares of card. As the tedium set in, I thought about the children without fully developed fine motor skills who might be more able at Computing, but would struggle with arranging stuff on tables. Then I thought about the ones with poor spatial awareness who bump into tables. Then I thought about the door opening on a windy day . . . and so I did this instead. The squares should snap to the grid.
