This is a regular potato chip. It was eaten shortly after this picture was taken:).
So what is it doing in the chip gallery? Well for one, we like potato chips here at the IIS. We hear so many microchip-potato chip jokes it only seemed logical to include one in the gallery as well. Some of us are also concerned that nobody actually checks the chips in the gallery, so we see this as a test. Let us know as sooon as you spot this chip :)
Congratulations to Peter Luethi :-), the first one to notice Potato on 23rd of September 2012. It has been only 4 months.
