One day, I would like to visit some country that wants their own particle accelerator like the one at CERN in Switzerland. I would offer to build one for much less money. 2 years and 100 million dollars later, I would announce completion of the machine. It would mostly just be fiber optic cables and some LEDs and maybe a laser. I'd proudly show it off to the leader of that country and his Minister of Science and announce "With this machine, you can now accelerate photons up to near the speed of light." Maybe they will applaud. If they mention wanting to do the same thing with protons, I'll tell them they have to purchase the upgrade package for that.
