YouTuber builds 8-bit CPU in Excel showcasing app's unexpected versatility

YouTuber Inkbox has built an 8-bit RISC CPU in Excel, following a previous 16-bit version. This new CPU can draw a rainbow on the screen and operates at 12-14Hz, a significant improvement over the earlier model's 1-2Hz. Excel, originally designed for spreadsheets, is now being used for unconventional projects like this CPU, as well as games like Fallout RPG and Tetris. These creations highlight the app's versatility beyond its intended purpose.
