DIY lightpainting box
Ok so a few people have asked about the lightsource used to create the image in the link below:
Its simply a homebrew box made from foam board which was lying around. This stuff is very light, easy to work with and has a slight sheen to it which is good for reflecting light. My MTB bike torch then pokes through one end, and illuminates the box. Its wrapped in insulation tape to prevent light leaking out of the sides.. and thats it.
