I've tried folding for a little while and actually not sold any of the tokens I've earned, but was wondering if there is any use aside from a speculative investment for someone to purchase the tokens. A while ago, I had some Gridcoins since I really like the concept of providing unused computing power to worthwhile efforts.
One thing I always thought would be cool would be if you could use these "science oriented" tokens for purchases geared towards the science community. A big one I had thought of was using these tokens to buy tickets to the Smithsonian Institute of Arts or other museums that promote science. When people go to these types of places, they are in an open mindset where they may actually read a small description next to a computer humming away in the corner of the room that is folding proteins. It would be awesome if people could at least pay for a portion of their entry fee in whatever FLDC they earned prior to visiting such a place.
