This post recyled from October 2005.
If you are artistically-minded, get a large pumpkin and carve a nice "Jack O' Lantern" this Halloween (yes, all puns are intended).
Click >> here for a pretty large pattern to fit a good-sized pumpkin. You can enlarge the picture you see by going to the bottom right of the picture and clicking on the expanding arrows that should appear. This pattern is 800 pixels wide.
Transfer the pattern with pin pricks through the paper into the pumpkin.
Carve the yellow parts of the jack very deeply, but not so deeply as to go through the entire pumpkin. The goal is to leave a thin bit of yellow pumpkin flesh which the light will radiate through. Again, use the needle to ascertain pumpkin thickness.
If you need a larger or small pattern, simply increase or decrease the pattern size on a Xerox machine.
