I finally decided to start cleaning, or at least tidying up, the house today. So I come across a few things I had picked up when we went to AstroFest last year, a sticker of the solar system. It had the individual plants plus the astroid belt and instructions on how to place them so the distances are roughly to scale. They recommended using a receipt paper roll. But I didn't have that handy.
So I looked around and selected the kitchen tiles (so the stickers wouldn't damage the paint, and I could easy take them off if it looked ridiculous). The section is about 1.5 metres (7.5 ft) wide so they're spread apart nicely, and right above the sink.
It does look a bit odd and nerdy, but maybe it'll make washing dishes a bit more thoughtful.
