Looks awesome JCO, I might build the same thing this year.
I have bought monsterguts before but I didn't realize that "PMW Pulse Motor Controller + Record" controller existed. That record and speed control will come in handy for a lot of possible props. Figures that they are out of stock now....yeesh..
"PMW Pulse Motor Controller + Record" seems to be back in stock, so just got it. I agree, without the randomness of the thumping that this controller allows, I think the monster in a box gag is much less effective. I'm excited that this will be a room of my Frankenstein castle that has a big impact.
