MadLight sends Artnet signals.
With the proper card (such as Enttec OpenDMX), you can convert Artnet signal to DMX signals, which are used to control lighting equipment.
Think of DMX as the equivalent of MIDI, but for lights.
So any device that is DMX compliant will work with MadMapper.
Controlling moving light (such as clay Paky) is theoretically possible, however, you'll be driving PAN TILT (= movement) with pixel data, which might be awkward in some situations.
A tutorial is coming on that subject.
controlling MAdMapper from a GrandMa was already possible - since version 1.1-, as MadMapper accepts DMX control data as an input
