Imagine a custom 8bit CPU that is designed to draw art. The CPU has 256 bytes of memory, two registers (PC and SP) and two addressing modes.
Unfortunately the main memory is very volatile, causing bits to randomly flip. When the bits change - so does the program.
Watch the literal results of a computer program glitching.
Click on the glitch modes at the bottom. In manual mode, click on the memory bits themselves to toggle them yourself. Use the list of programs on the right to load different base programs.
