Spontaneous LED wall drawing event

October 16th, 2010

I’m sat in front of the LED wall on which you can draw through Colorillo for an hour or so and asked the internet to draw remotely. Fun!

Here are a few photos of pictures that were drawn:

Back on an LED Wall

October 14th, 2010

Colorillo is back on an LED wall! Again located in Vienna, this time on the Künstlerhaus Wien in the course of the media architecture biennale, a conference and exhibition of media walls and fascades.

Quite a few interesting aspects to it:

  1. the wall goes around a corner
  2. it is embedded into the logo of the conference
  3. the LEDs are aligned more densely this time
  4. a special version of Colorillo is being used that is capable of pixel drawing

The exhibition is worth a look, too. Lots of techniques for enabling colorful light constructions. Also check out the gallery I have attached to this post.

The wall is on display until October 31, 2010 and is turned on at dusk. The exhibition runs daily from 10am to 6pm, on Thursdays until 9pm. Come by and draw! (you can find the URL for drawing right next to the wall)

Thank you to Oliver Schürer, Wolfgang Heigerth and Manfred Wuits (and many others) who were involved in the project!

HOWTO: Ignore Mischievous Drawers

August 16th, 2010

Because this question arises from time to time, I want to show you what you can do against mischievous drawers, who tend to overdraw you or draw offending things: You can simply ignore them.

Let me show you how I deal with such people:

First, I’m just drawing along…

… then, a stupid guy comes along and overdraws me

Now I need to find out, who this was. In this demo case it’s easy, but when there are quite a few people in the room this might get difficult. Click on the pen icon of the user: the last line of this guy will be highlighted on the drawing.

Next, I rename the user, so that I can identify him or her later on. This renaming just affects how this user is displayed to me. This step is optional, of course.

Finally, I ignore the user by clicking on “ignore”. Now any future lines drawn by this user will be ignored (and just for you). Unfortunately the lines that already have been drawn, remain.

This user might continue to overdraw things, but that I don’t see anymore.

Currently, this ignore feature only applies to you. The user is not automatically ignored for other people yet. Also I am considering to remove the lines after the fact for this user, but I am not yet sure if it’s necessary. You can tell me otherwise by feedback or in the comments 🙂

Always remember that you can use the playback feature to undo the lines and then go off to a private room and invite people to come along.

15 Million Lines

August 10th, 2010

Just a quick note: Tonight we surpassed 15 million lines drawn on Colorillo. Actually this is just since around January 15, 2010, because only since then I store the lines in a database.


Thank you for drawing! Now we aim for 20 million lines 🙂

Update: Pressure-sensitive Drawing

August 4th, 2010

Good news, Wacom has updated its plugin to version 1.1.0.5 and it now works again in Firefox 3.5+. So if you have that browser, reinstall the plugin with the new version and it should finally work.

Change what pen pressure controlsI have also added a (what I consider pretty useful) feature for people who use the Wacom plugin:

You can now change what the pen pressure affects. Previously it automatically applied to the thickness of the pen. Now you can disable the pen pressure temporarily or change it to affect opacity. There is a keyboard shortcut for it too, just press the letter p to cycle through it. Thanks to Dionix and Anonymous for the idea!

Please tell me if it misbehaves, I’m not a great expert in drawing with a tablet, so I rely on your feedback 🙂
