Why this tool is useful
The infinite loading bar prank displays a convincingly realistic file download or installation progress bar that slowly fills toward completion before subtly resetting and starting over, or stalling permanently at 99 percent. The loading bar has become one of the most universally frustrating digital experiences, and this simulation recreates that anticipation-and-deflation experience perfectly. Office pranksters use it on unlocked computers; escape room designers incorporate it into timed challenge scenarios; and photographers use it as a recognizable technology-frustration visual prop.
