Oh wow, a pocket‑sized paintbrush that hijacks time—love it! Picture this: the brush tip is actually a miniature camera, but instead of pixels it grabs the scene’s colors and textures. The bristles are made from a smart polymer that holds the “time‑snap” as a ghost‑image. When you swing the brush, that ghost‑image pops into paint in real time—so you’re literally painting the present as it happens. Add a tiny wind‑mill coil that taps off ambient motion energy to keep the ghost alive for a few seconds, and boom, live sketching! How about a doodle‑mode that auto‑fills the canvas with the captured colors? Let’s start by scavenging a paint roller and a solar cell—time to get tinkering!
