You just scrolled into a piece of paper.
Not a real one obviously. But the folds are real, the grain is real,
and the creases were written by hand in GLSL. At Codegrid I spend an
unreasonable amount of time on details like that. The kind of details
nobody notices until they are missing.
That is sort of the whole point.
Every tutorial on the channel starts the same way. Someone says "what
if I tried this" and then three hours disappear. The result is usually
a few hundred lines of code and a scroll effect that makes at least
one person in the comments say "this is insane." I live for that
comment.
