Chris Baker of Hauntcast has mad-propped my Haunted Tombstone projection effect in this month's episode (#40). Go pick up a subscription if you don't have one, and have a listen. I haven't been tuning in for a while, but this was a good episode all around. Besides, you'll get a few cool details about the creation of the Haunted Tombstone in the "Mad Props for Props" segment (which starts at around 1:40:40).
Don't forget you can purchase all of my Haunted Tombstone projection effect videos here: Haunted Tombstone.
