Mapping MP's expenses

With all the furore over the abuse of the expenses system by some MPs there have only been a a few mashups appearing shedding light on the fiddlers.

This map from OUseful shows travel expenses. Interesting to pick out the couple of exceptionally high bills from the MPs for Luton and Epsom for example and the MP from Coventry NW seems to stand out from those around him.

Surely there are some others out there?
