The mat display features Bill Gates’ personal autograph from his 2025 memoir, “Source Code”. We designed this mat with an early photo of Bill from 1975, the year he co-founded Microsoft and some of the actual code first written by Gates and Paul Allen. Their work helped ignite the personal computer revolution, shaping modern software and laying the foundation for how the world learns, works, and communicates today.
