How to make a light that turn on and off (Lightswitch) easiest way!

Nice dude

I like it

That's really cool. Imagine a long hallway that has light switches like these, the slowly turn on one by one to reveal a Cake at the end of the hall. Anyone willing to build this? This reminds me of that once scene in Incredibles.

Looks nice

Interesting, thanks
