If you are looking for Halloween pumpkin carving ideas, here are some classic tech- and sci-fi-themes. I sure like R2-D2 more than Darth Pumpkin and Yod-o'-lantern, but the most terrifying is the red ring of death pumpkin.
You got new ideas? Start carving, because someone tells me that next week there will be a contest coming up. Head to Unplggd for the complete gallery, including the best Mario of all times: Raccoon Mario. [Unplggd]
