Somewhere near the admins, Jester is watching. Everyone. Everything. He will give you a gift, if you show him where to send it...

NOTE: you'll have to go to the hardware village (MB 3rd), where Jester is sitting. Ask our volunteers if you're not sure where it is.

About Big Jester

At @Hack 2025, Big Jester featured a mysterious box with an all-seeing eye (just a cheap webcam). We're sharing it - along with the included picture - as a fun throwback. However, since it only requires a webcam, you can try running it locally using the source code available in challenge's public repo.
