3 Random Bob Challenge: Shell

Home from work and not much time to blip, I rummaged about in my jar of shells and found this bit of urchin shell which had broken in 2 down one of it's seams. These shells fascinate me, the way they break apart in zig zag lines.

A quick stop in at the In Laws for steak pie and now back home. Gorgeous has just presented me with a welcome home G&T :D
