Well, I'm currently at work, but have some spare time on my hands as I'm waiting for a male-to-female 9 pin serial adatptor (stupid pc ), so I was curious as to what interesting things other memebrs are doing this summer. My job is actually summer research (although in my case its not exactly research) in the physics department of my college. I'm using the department's Intensified Pentamax camera system (a really really sensitive, really, really expensive digital camera) to capture images of quantum interference of individual photons in the double slit experiment, using a laser run through polarizers to a very low insensity (it cannot be seen when an object is placed in the beams path), then run through neutral density filters until the laser beam is down to a measurable rate of photons which then produce an interference pattern on the CCD of the camera. The interesting thing is that the interference continues to occur even when the rate of photons has droppped to one photon moving through the double slit at a time; under classical physics the photon should continue straight after passing through the slit, as there is nothing for it to interfere with. However, due to the laws of quantum machanics, this does not occur, and a diffraction pater will appear if you let the images accumulate.
