Colors! Wade Brainerd, Jens Andersson, User:Loser

Colors is a simple natural media painting activity for the XO laptop, based on a Nintendo DS program by Jens Andersson.

Rather than constructing images from geometric shapes, the user is encouraged to keep painting on their work until it looks right, starting with rough strokes and then adding extra details.

The activity features soft brushes, collaborative painting, the ability to watch tutorial paintings as they are painted, and a variety of input methods including "video paint" using the webcam.

You can see some art that has been created with the DS version of Colors! here: http://colors.brombra.net/

How to Install

Download this .xo file using the Browse activity: Colors!-13.xo

Wacom Support

Colors! versions 11 and above support USB Wacom tablets, such as the Wacom Bamboo ($60 at Amazon). Wacom support requires OLPC Software Release 8.2.0, so update if you are on an older build.

To use your USB Wacom tablet with Colors, you need to do a little work at the Terminal.

wget http://dev.laptop.org/~wadeb/setupwacom.sh
sudo sh setupwacom.sh

This will install the linuxwacom package, download and install the Wacom kernel module, and download and replace your Xorg configuration file with one that supports Wacom tablets.

Restart your XO and launch Colors!. Voila, Wacom support! Check the Sensitive buttons in the Brush Control screen to enable pressure sensitivity for brush size and opacity. --~~~~Insert non-formatted text here ---- <s><br />Strike-through text</s>

Development

Colors is a standard Python activity that uses PyGTK for graphics and events. The canvas is managed by a custom C++ extension which handles painting, recording and playback, rendering to the screen, and loading and saving. All source code is included in the activity bundle.

Please see the Colors!/Development page for bug lists, todo lists, build environment instructions, etc.

Testing

Colors runs well on B4 laptops and build 656, however its development status is alpha and there are known bugs. It is functional enough to be used by children though, and bug reports are welcome (see the Development page).
