Thanks so much

@michel @dbini @Reinhard 

...for your different solutions, all of which are expanding my understanding of how to program switches and triggers in Isadora. Using the Trigger Value actor as a binary 'on/off' switch is powerful. Monty talks about this too. In the end I went for a mouse watcher with no modifier triggering a zero/off, so that i can toggle between on and off using the modifier i set for the first Mouse Watcher (img). This is good, but following the tutorial advice, I am now playing with the Stage Mouse Watcher to get something closer to the kind of 'touch = 'on' / release = off' experience. 

Thank you guys, so far! This is really a big help!  I will try and rebuild it. And maybe cut out the on off in the left hand, if it is even necessary...  I did try to take the on/off out at one point - but I will start trying to rebuild and see if I can get it to work again! Thanks for the support!!! 

@Mark - what I can say right now is, that if the leap motion freezes - usually it happens for all the scenes and I have to restart my computer... but this time it was only this one - so I think it is another problem. but I will go through the comments so far and see if I can work it out:) 

Maybe one could have the option to choose the coordinate system. This would allow progress and still support old pages...?

A very simple version of this can be accomplished, by using a live camera input (you may need to play with back vs front lighting).

Then applying a Threshold actor (to create a black and white only version of the video input). Then the Edge actor (this will trace the edge between the white and black) providing the outline.

You can then send this outline/shadow to any outputs and/or mapping you like.

Together with the visual artists Marcela Rapallo and Rafael Arévalo Peñuela we were testing the possibilities of staging with Isadora software and the new configuration effects on the stroke: sustein and evanescences -fade outs- in real time, using a MIDI controller as an interface physics between the graphics tablet and Isadora.
The new plug in "Live Drawing" created by @mark  provides a thorough control over the most important parameters in relation to live interactive digital drawing, opening a new field in visual experimentation.

Sometimes sleep is good 😛

I got around the problem a little bit. I've not managed two tablets but:
I have one Wacom tablet using Osculator, which has the option to disconnect it from the mouse function, so you can simultaneously use the trackpad. 
I'm also using Touch OSC on an iPad which has an xy-pad feature that works like a graphics tablet for the x,y axis at least. There's a little latency but you can do it via usb as well.
I've seen that it's possible to connect two computers, using Osculator on both. That way you could use a graphics tablet on that one and transfer the OSC data from one computer to the other. This sounds like the most promising method, though I've not managed to get it to work yet. I only just had a quick go though so I'm sure it might work.

Happy Pride!

Hi ! anyone has experience with the px-pen graphic tablet ? I just bought one. Here is a patch for drawing works pretty ok using the mouse. But with the pen is not working properly: is always drawing. Thats the maine problem, also the relation between the tablet and the stage area

Thanks a lot !!
