In total there are three 4th #Bitcoin halving block pieces with a steel surface.

One was made for the nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3 office, one will be on display at the BTC24 conference in Nashville and auctioned off via nostr:npub1rujwkh9c3jnq70g3v62rrm6m7pxqsz25675narm74q9emcwqltjswe00fg and one I will keep for my own atelier. 👀

And yes, 288 LEDs have been installed and it can light up in any color you want. 🟪🟦
