I've spent some of today adding in a photo gallery application to the ROOL site and you can now find my own pictures from Wakefield here:
https://www.riscosopen.org/photos/projects/show/1
Some of the pictures make it much more clear which things are mouse mats and which are coasters
We intend to produce a second run of 100 mats and 200 coasters which we'll sell through the web site and/or at whatever other shows, user group meetings etc. we attend in the future.
