Painting with light

I decided to give this a try, it is mostly scribbles as I have not perfected the art of writing backwards. My husband had this neat LED pen that changes colors so I set up my tripod and went into a dark room, and set the timer and used a long exposure and came up with these.

This was supposed to say Hello

This was done with the LED pen and one of my son's light up toys

And this one is supposed to say Love! can you see it?? LOL!
