My profile picture is a photo of a cobra holding a Tux plush and my ThinkPad.
There have been many iterations over time. The ones that I still have are listed here. All of my contributions are licensed under CC BY-SA 4.0 International.
Zeroth iteration (XCF file unavailable)
This version was created by a few people on Matrix, namely AIM and Ulfnic.
First iteration (XCF file unavailable)
This version is a modified version of the zeroth iteration, using my ThinkPad.
Second iteration (XCF file)
This version is completely redone, using the original cobra photo from Wikimedia, and a picture of my ThinkPad and Tux plush. To make the shadows, I copied the Tux and ThinkPad layers, made them black, and turned them slightly transparent. I also used the dodge and burn tool to adjust the lighting on them. I added a little shadow on the Tux plush to make it feel like it was really touching the cobra.
Third iteration (XCF file)
In this version, I added a trans flag to celebrate my coming out. I used the paintbrush tool in HSL Color mode to get it just right. I might go back and make it actually look like each scale has the color, because currently the color goes over into other scales.
