DSLR: Playing with Light

I’m progressing in my use of the Canon DSLR. I think I have achieve proficiency, and am now experimenting on becoming good with the camera. I did a series of photos last night where I left the shutter open for for more than a few seconds and “painted with light.” I the images below, I went into a dark room, opened the shutter for five seconds and “wrote” on the wall with a laser pointer. You can view the whole set on Flickr.
