It's Wheatley, Potato GLaDOS - or in this case, gourd GLaDOS, and a little tiny pumpkin turret. It's not on here, but there are two LEDs on the gourd GLaDOS that light up, and behind the pumpkin, we had a little audio box playing sound bits from the game. Oh yeah, and there's a crow there to torment and frighten GLaDOS. woo.
This was technically entered in our workplace pumpkin carving contest thingy that we hold each year. This date specifically - Oct 31st - is our GM date, so everyone is busy and exhausted and burned out. Thanks to this, there were only 3 pumpkins even entered. lol. Which means that it's a guaranteed win because there are prizes for 1st, 2nd, and 3rd places. I believe the prize is a gift card for the sony style store where we get our employee discounts. Still, it was fun.
