LiDAR or "light detection and ranging" is a way of working out and picturing the distance to an object by shooting laser beams at it, and timing how long it takes the laser to bounce back to the scanner. It's been used for a bunch of Hard Science-y purposes, from mapping cave systems to measuring changes in the Amazon forest canopy. It's also become popular among artists, who use it to create high-fidelity yet abstractly coloured and ethereal visualisations of, for example, rivers. Now here's LiDAR Exploration Program, a "relaxing atmospheric horror" game from KenForest, in which you roam maps with a handheld LiDAR gun scanning the geography into being.
