Effectron is an app that constantly draws effects in the real world. It is developed by Anffexion Inc. and allows users to draw 3D effects in real time on terrain acquired from the iPad Pro’s onboard LiDAR sensor. There are 20 different effects to choose from, and it is possible to turn your home into a grid-covered space like in the movie TRON, or turn your office hallway into a cave to explore.
