The images presented below and on the next page were mostly created on a fairly basic HTC Wildfire S mobile phone, using SourcesPro. They have not been retouched - all that has been done is to lighten some of them somewhat as the brightness of the displays on Android devices appears to produce rather dark files. I will see about producing a utility for doing this adjustment for those of you without access to an image manipulation program. On higher powered devices, such as the Nexus 7, the pictures can be up to 4000 pixels on the long side. It's a trivial matter to create bigger images by tiling the area you want to render and then join the individual pieces together in an image editing program such as Photoshop.
The images here give little impression of how vibrant the originals appear on an Android device with a decent screen. Note, if you view the galleries web pages (Sources or artwork) on a mobile phone, they may appear lighter than normal.
Some of these designs are now available to buy as prints, cushions, mugs, phone covers, even jigsaws! on Zippi:
