I kept pausing the same anime episode to get back to work. So I built BackDrop_. It plays any local video (MP4, MKV, AVI, MOV, TS) as a transparent overlay on your full Windows desktop. Opacity from 0–100%, mouse clicks and keyboard pass through to whatever's underneath. No cloud. No account. Files stay on your drive. One-time payment. Works for anime while coding, news overlays for traders, or ambient video while studying.
