This morning I have had great fun with this!
The University of St Andrews Face Transformer Image Upload.
If you get the right photo it gives you some really cool results. I tried three because I have time on my hands (and didn't read the instructions properly...) These are from the last one I tried - a picture of me with purple hair from the RFN thread.
It's for fun only of course.
For the record, Black Cherry and Botticherry.
