Vault.New?

Hi! Daw here, I found this world i made 2 or 3 months ago and was wondering if this is something new or, something I built because I saw someone do it, or this might already be a thing and I don't know about it

I am fully aware item combination locks are a thing but I mean using 1 frame for 2 or more locks in a timed manner

Please check it out and if it's new, tell me and maybe spread the word! Don't forget to give credit.

If it isn't new, show me a vid or a project pls. Something with a date on it. Thanks!
