Draw pictures and write letters with CNI laser pointers

How to use a laser pointer to draw, to write and to record it? I think it is a very interesting thing. With the help of a camera with the function which could set longer exposure time,you could easily record what you draw and write with the laser pointers.

I think it is done on a surface painted with fluorescent paint. The 405 nm is close to UV and lights up the paint.
