The fine people over at Marcansoft.com have generously created a new open-source set of software called OpenLase to control DIY laser projectors in real time… and the results are top-notch.
Using an audio card to control the lasers movement, the applications for this software are almost limitless. Below you will find videos showing experimentation with real time gaming, audio visualization and even an interactive 3D harp that is playable, all displayed by a $270 projector.
As of yet there is no documentation for the software, but should there be enough interest there is the possibility that a manual or at least support will be offered. To find out more about this project or to get your own copy, check out marcansoft.com.
