I have been animating this video over several weeks, and now it is done.
It's a video about the PNG image format.
The text is taken from the very 1990s-like list of spiffy features from An informal history of PNG, on the PNG website. It was probably written in the actual 1990s.
It is read by my friend flicky and the music is Neon Laser Horizon by Kevin MacLeod of Incompetech.
Why did I make this? I dunno. I just wanted to. Colour correction has a huge bunch of maths behind it which I did my best to implement in Blender for a few seconds of animation.
