I've always wanted to have a go at these, so I put the new camera to the test. Physiogams are nothing more than painting with light. So you can write your name with a torch or suspend a laser light from the ceiling like I have here. They're only tests. You can tell that from the third one where you can see the tripod leg. For the second and third I attached a small glass bottle to give me random lines. I'm going to see if I can get hold of a white laser and use sweet wrappers as filters to change the colour.
