Running Through Time

Time for more bokeh! Done in GIMP 2.6.11 on Fedora 15 "Lovelock"; released under Creative Commons Attribution-ShareAlike terms. (CC BY-SA)

UPDATE 1: Stripped off ~131.6 MB of leftover layers and added in the following colors: Blue, Electric Blue, Rust, Midnight Blue, Electrum, Lime Green, Orange, and Darker Pink. Curiously, despite the 60 MB net reduction in combined file size, the archive is actually 2 MB larger. Probably because less of the data is redundant now.

Included in the 7-Zip download are:
Running Through Time - Original
Running Through Time - Red Dawn
Running Through Time - Steel Blue
Running Through Time - Yellow
Running Through Time - Pink
Running Through Time - Green
Running Through Time - Blue [update 1]
Running Through Time - Electric Blue [update 1]
Running Through Time - Midnight Blue [update 1]
Running Through Time - Rust [update 1]
Running Through Time - Electrum [update 1]
Running Through Time - Lime Green [update 1]
Running Through Time - Orange [update 1]
Running Through Time - Darker Pink [update 1]
...and all the original .XCF project files. I tried to clean up as many extra layers as possible
