How to Make Magic With a Permanent Marker

I've been MIA recently because there's been a lot of stuff going on in my personal life to you like I'm not sure if I want to live in California so considering possibly moving either either from different place in LA or just out of state. Also trying to replan videos for the channel and also trying to repurpose it for something else but that is one of the videos I wanted to do was sort of actually showing it built for thatBecause I could also use that build as sort of a base for a robotic arm or something later onlike repurposing it forsomething else.
