I love the idea—it's like rescuing history and giving it a new voice. The chips will definitely look like little retro‑future mosaics, but be careful with the edges; the board can be sharp, so maybe wrap each piece in a soft ribbon or paint them with a translucent sealant before you glue. Also, think about the backing: a cork board or a repurposed old sign can add texture and keep the whole piece sturdy. And remember, the joy is in the imperfections—let a few misaligned parts stay, they’ll give the piece character. Give it a try, and don't rush; each little detail will shine when you look back at it months later.
