# Colorillo

October 22, 2009

Currently I am doing my civillian service in Austria (though only 1.5 months to 
go), but in summer when I had a little free time I built something small and neat:
Colorillo.

[⌊Colorillo⌉⌊Colorillo⌉[

[Colorillo](http://colorillo.com/) is a very simple drawing program on a web site.
What makes it particularly fun is that you can **draw together** with other people.
Whatever someone draws on the page you are currently on, you will see right away.

Colorillo makes use of a [plethora of interesting technologies](http://colorillo.com/about.php)
to accomplish simultaneous drawing. Among them are:

 * [HTML5 Canvas](http://en.factolex.com/Canvas:element_html)
 * [Comet](http://en.factolex.com/Comet:programming) through [orbited](http://www.orbited.org/)
 * [rabbitMQ](http://www.rabbitmq.com/)

Then in October I got the chance to bring Colorillo onto the LED wall of the [archdiploma 2009 exhibition](http://www.kunsthallewien.at/cgi-bin/event/event.pl?id=3224&lang=en)
at [Kunsthalle Vienna](http://www.kunsthallewien.at/), so at the moment you can 
stand in front of the building and use Colorillo to draw on it. It’s fun!
