Abstract Thursday: Patterns

I had fun with this one - thanks Ingeborg!

This started off as a photo of a holder for spare toilet rolls - it's a cylindrical chrome-plated "cage" with a translucent liner. So I put a torch inside it and took the shot. The photo was then turned on its side, duplicated on a layer and fiddled with it in Photoshop to produce these patterns - I quite like the 1960s psychedelic effect!
