Projection mapping usually means a laptop, a heavy desktop suite and an evening of setup. SurfaBeam puts it on a touchscreen. Add a surface, drag the corners onto the real object, bow the edges into curves for a pillar or a pumpkin, mask the spill, drop in a video. Same toolset on Android, iOS, macOS and Windows. Camera-based hand and body tracking, a timeline for sequencing a show, and export to a video file. Free forever with a watermark; Pro removes it and unlocks save, load and export.
