If you look, then at some pictures you can see the figures of people. They are using lasers and make the "picture". But that, of course, not only in this. Even using the correct shutter speed when shooting.

Exposure time should be long enough-minutes, in time to make the image vsetyashimsya objects. "Illuminated brush"-can be seen (where it came across) are called similar tehnika.Proby mozhnodelat conventional Digital Cameras in complete darkness (though a match) when vyderzhke1-3minuty. (In my primitive such vyzherzhku can not be established, but it has long been used to try)
Who has those capabilities allow, to make a sample-minute thing!

Added after 14 minutes
Luke, try it! Easy!
