Light Drawing

I thought that a photography process i had heard of called light drawing would be great to look at for the CD cover inspiration. Below are some images of light drawing/ light graffiti.

The colours used in this picture are great and i love the crazy nature of the image drawn.

Using light graffiti on an existing object looks great but I think it looks hard to line up in the right place. With the light not lining up with the actual strings of the guitar this image looks a bit messy, however it does add to the effect of the whole photo somehow. 

The images below are taken by someone that i know who i will learn how to do light graffiti from.

I plan to experiment with my own light drawing asap.
