GimpyMcJackass writes "With Halloween just around the corner, Dremel has "developed" the ultimate pumpkin carver set. It actually looks like it's just your normal dremel (although it's translucent orange) with a 191 high speed cutter and some fancy patterns. Of course, if you already have a Dremel and cutter (or reasonable knock-off of either/both), then you can just download some patterns."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
