Our Halloween theme this year was “Heroes and Villains”. I thought it would be fun to do a City skyline as one of our pieces. The pieces are cut out of 3/8 Lowe’s Luan. I dadoed a slot in a 1x4 to stand them up in and hold them. The skyline can be changed by swapping the panels around. The light pipes for the LED lights are medium acrylic, driven by an Arduino. Backlighting is a set of cheap LED strip lights from Walmart.
