Joy in repetition

After a few days of rushed phone shots, I found myself a spare half-hour to sit down and create a half-decent blip today – for Abstract Thursday #AT448 (thanks to Ingeborg for hosting once again), which has the theme of patterns.

This one combines abstract with macro, which might *possibly* give you a clue as to what it is. I don't think any of you will get it though, so there's a (non-existent) prize on offer for correct guesses. It reminds me of Space Invaders somewhat.
