I thought I have seen everything! But no! I thought I got an original idea! But no! =D

For this picture I photographed a glass of beer, and then displayed it on my cell phone. However, there are also smart phone apps that shows you an animated image of various drinks in the glass, and the animation then reacts to the phone movements and directions!

So, although you can't make something like real coffee with your smart phone (yet...), you can come up with as crazy ideas as this!
