First of all thanks a lot for developing this very versatile/enabling tool!
I am using it to do an OSC robot controller as it is very convenient in the development stage to quickly change my user interface. But now I would like to do something a bit specific, and I am not sure if it is possible.
I would like to use a widget to draw a polygon that I can interact with (plot widget?), such that by touching the plot I can deform that polygon. The angle between the lines of the polygon will then be sent as OSC parameters to an arduino to control some motors (arduino side is figured out, communicating with OSC).
