I went to EMF Camp at the weekend and we took our laser cutter along so I ended up making a few things while I was in the field. Sadly I couldn't find my camera cable so I couldn't blog from the field but I can add them for you now.
KateMonkey wanted something a bit more solid to for the body of her Nyan Cat so she supplied the files for the outline and I laser cut one out of mdf for her. It was then placed at the top of a 10ft pole and we got to wave it around maniacally. (svg here)
