Ever see things in clouds (other than your rained out picnic)? I often see things in images. Especially old black and white illustrations of machines combined with a modern setting.

I also considered what scanning vegitables would look like. Sliced or not, the scans turned out quite intriguing. Try it sometime. You'll need a scanner with a method of blocking out light (my scanner has a two part lid which is, I think no longer available). Then have fun at the store.
