First off, try some astrophotography. Aim the camera on a tripod UPWARDS with no flash, and just set the shutter to 'B'. Leave it out from 1 hour after sunset to 1 hour before sunrise and see what you get.
If you are willing to dump the Kodachrome, get some 3200 speed film (Ilford is good), and use the flash with it. You get an AMAZING range and a nice grain. Who knows what you will get.
