Like the jack-o-lantern? I built it myself! Happy Halloween from your favorite deranged bearded LEGO maniac.
The inside of the pumpkin is hollow, and rather than constructing an elaborate electronic circuit, I simply taped a few red LEDs to a large 3V coin cell and placed it within. This was shot on a very, very cold early morning in a church cemetery in East Petersburg, PA. After my birthday in late October, I drove to my hometown for the weekend, whereupon I shot the photo. I tried multiple shutter speed and aperture settings to get the correct shot: in the above image, I used a low F-stop, and in the bottom image, I used slow shutter speeds with my cell phone camera light placed near the pumpkin. Hence, the bottom image has the grass illuminated.
