I'm personally into copying (ah, the blessed word "tribute") some of my favourite tickle pics. Its a challenge because I like to try to get the facial expressions to match. Got the idea from your copy of thebed tickle art pics (some of my favourites, incidentally).
I think there's a load of potential in this concept, if you can find the models to match the original.
I may not be posting myself for a little while. Have a huge marketting project starting (unexpectedly) for my games so will have to finish a 3d pic I'd been working on (my excuse for buying Poser and all my models in the first place!).
regards
R.
