Wednesday, took delivery of a Bat Detector. Sounds silly, but when Josh and I went on a bat walk at the Wetlands Centre in Barnes I was fascinated by the experience.

The detector translates the ultrasound produced by the bats to an audible sound on a loud speaker - the effect is wonderful. It's like listening into a hidden world with it's own dimensions. The clicks of the bat echo like in some large space - a cathedral perhaps. And it's not only the bats. There are insects too which can be heard clicking away.
