Ideas for image morphing?

Any ideas on how to do some sort of live slow morphing effect between a number of static images?

Like any other popular graphics effect, the technology behind "morphing" is well documented if you look in the right places. It is mainly a matter of digging through white papers and plucking out the relevant concepts. You will probably want to spend some time looking at OpenGL, as t0gg1e4u suggests.

I think what we're going to go with at the moment are some video renders using Norrkross MorphX http://www.norrkross.com/software/morphx/ - that was the kind of 'morphing' I was looking to do - plus some live bitwise xor crossfades from tutorial 9. I'll look into jit.repos as well.
