The first logo of Zeyn has been a blue gemstone very similar to the current logo.
I am unsure about the exact color values or opacity, but the gradient matched the current one.
The original logo was 30 by 30 pixels. Come to think of it, 31 by 31, I believe. I believe the parser had been implemented by then but only the "triangle" operator existed for drawing shapes. That operator did not ensure "precise edges". Adjacent triangles always overlapped by 1 pixel because the algorithm just drew Bresenham lines between the given points and filled the space between. This means that the pixelated triangles overlapped by one pixel on all of their adjacent edges.
This logo was among the first few images that I ever generated using Zeyn.
This is a recreation of what I consider the very first image ever generated by Zeyn. When it was generated, the parser did not exist, I generated it using three calls of the "zeyn_triangle" function.
Everything generated before was just a few white pixels, maybe a white line.
And I'm not sure if I used Farbfeld output for those,
or just printfed the pixel coordinates.
The image nicely shows off the normal blend mode used for the three partially transparent RGB triangles overlapping.
Later I also recreated the first.zeyn image from memory in Zeyn syntax
instead of the method calls that I had deleted at some point.
So I guess this is the second recreation.
