I heard you are not having fun enough with d today.
Do you know you can do things like this with dlang now? After
some fiddling with it, my last commits made this possible.

Sorry for the potato-quality video. My art director is on
vacation.
I am cheating a little with OpenCL since things are not fast

Enjoy!
I am facing strange ffmpeg errors on Windows. It fails to read a
frame. Do you have any ideas how to solve it?
Here is the error:

Also, it does not work on MacOS as well due to `glfw-d` not

Do you have any better solutions?
