Thanks Ryan.
We track the pens with an IR cam.
And yes this app was written in processing but, that was actually the last time we used it. Now we have written it in Open Frameworks.
We get much better speed and a more reliable app.

Thinking about it

If we get invited or there is an event that requires it, for sure. I would love to go to Vienna

Thank you George
Judging for the complexity of your QC work you are doing these days, I am sure you could pick it up easily

Thanks for the faith... and your general "openness" about your process and helpful nature.

It is the stuff like this that I am CONVINCED is the future of art.... it is basically not a "new" media... but it is slowly (and maybe even quickly!) morphing into an entirely new media from what people traditionally expect out of a "computer program".

When people interact with this stuff, it's not like they have in their minds "oh here I am playing with a computer program, la dee da"... it is a powerfully visceral reaction. It is even more attention grabbing to people than video games, internet, etcetera.

I think the fact that the stuff "interacts" with the viewer... and can "blur" so many types of traditional media... is something that brings out the same kind of wonderment that people had when they first saw film, or heard a record (well, maybe not that intense, but as close as we can really get to that in this day and age with an art medium).

I'm sure you have had that experience where people are messing with something and you can see in their faces that they almost can't believe what they are seeing....

To stop digressing.... was it fairly straightforward to port the Processing to openFrameworks, or did you end up having to "recode" a lot of it?

plans?
lots of plans :)
and yes it is possible

Dance Music by Errors

I don't think it feel frustrating when you us it, but we have been working to get as little lag as possible.
This video was shot the last time we used this app. For the new version we ported graffiti wall to C++ and the speed improvement was great.

It may be similar but not the same. We programmed this app ourselves

Basically it works like a spray can, if you hold it on one spot it will start to drip. We can also control the amount of drips and lengths of them in code.

thats pretty cool nicee

Thank you Sergio. Looking forward to getting together in the new year.

We use it at festivals, so it is available to the public. We haven't done anything in the states yet, most of the installation work we do is local or in Europe. Hopefully this year coming we will have a chance to go to LA, I will make sure to let you know.

Not really.
It is a rear projection screen and a computer vision system that detects the pens from behind the screen

yea my school just had those kind of boards installed into every classroom they re awsome. we call them smart boards (dont know their real name) but when the teacher is out or something we do stuff just like this on them. u can do it with your finger as well though and then save it on the computer.

Ohhh. Okay. I think alot of schools call it different things.. but this digital graffiti is cool, nonetheless.

Hey guys we don't use what you are talking about. This is a rear projection screen.
