Here we first have a series, the Alien Roses, so called because the original was altered using a GIMP filter called "Alien Map 2".
I uploaded this image to Flickr. During one of my coffee breaks at work I was sitting by the computer, looking through my flickr photostream and got an idea. I downloaded the original to my work computer, then went back to flickr and rotated it three times, saving each rotation on the computer. Then I opened fd's flickr toys and opened the Mosaic Maker toy and uploaded the photos, making two different symmetrical mosaics:
|Alien Roses I|
|Alien Roses II|
Then I decided I wanted to see how they would look as tiling patterns, so I did it again, this time with the two mosaics, and got this:
|Alien Psychadelica I|
|Alien Psychadelica II|
If you want to see how truly psychedelic they are, try setting them as your desktop background and choose "tile".
