Photo transfer gel
I used it for one of my projects at uni - It was more or less successful - I transferred photos onto (unstretched, unprimed) canvas and some photos turned out perfect, some less so. It worked for the effect I was trying to achieve, but for perfect transfers I think you really need to use a lot of gel, and seriously wait at least 24hours before touching it. All in all I think it's pretty good, and works well, but requires experimentation.
