The coolest program I'm running in easyDebian is the Lazarus Gui.

Now I can develop freepascal with a visual gui on the device.

(I'm running wheezy on a ext2/3 filesystem, on a 32GB card.)

You can design and compile directly on the device.
Or you can create a project on a PC with Linux, Windows or Mac and recompile the projet on the device. Then you can adapt the visual elements directly on the device.
