Macro photos

I got a set of extension rings for my camera a while back. Basically, what they do, is extend the distance to film-plane so that one can focus on things a lot closer than normal. They cost ~€15 from eBay, which is a damn sight cheaper than a Nikkor Micro (~€250) and almost as good in terms of quality. Ok, the Nikkor would give me greater than life-size reproduction, but... well, I'm only an amateur.

Anyhow... here's a few examples of how the pictures look:
