Jocko, I love the first flour shot, shows a real "punch" . Keep experience please I love these ideas, totaly out of the square if you know what I mean. 

I have to admit it was  a while ago but within a year I bought some neon paint, I painted my hand, stick it under the black light but did not came out a way your looks like. Most likely I used a wrong paint. I living in a small town we have only one art supply store, this is what they have only. I mentioned a neon yelly, they looked at me funny. So I have to put this project a side untill I find a way to do it. I love to play with low light and strong colors and hand. This project would be for me. 
I thought I let you know your ongoing project very motivating to try it out. I will do it one day, I just have to figure it how.
