Dejvino 8defef3ed0 Tell a dead shader apart from a boring scene in the gallery
A failed shader compile renders black, and black frames are identical to each
other, so every block scores 0.000 and the row reads as the least varied scene
in the library rather than as a broken one. That happened yesterday — the
subject helpers were declared above the ink they call, GLSL has no forward
declarations, the whole preamble failed to compile, and the gallery reported a
variety of exactly 0.000 with no indication anything was wrong. It is a
particularly bad failure mode for a tool whose entire job is ranking scenes by
that number.

A scene whose first frame has no luminance and no variance is now reported as
broken, with both figures and a pointer to the console, and the row is coloured
apart from the merely flat ones so it cannot be mistaken for a bad score. The
summary counts them separately.

Verified against both answers rather than only the happy one: a healthy Moiré
Grid comes back 0.0365 with no error, and a deliberately broken copy of the same
scene comes back with the diagnosis instead of a zero.

Recorded in HOWTO-variety.md alongside the other instrument traps, since the
general lesson outlives this instance — a broken render produces the most boring
possible numbers rather than an error.

Music Video Generator

After I'm done producing a music track, I still need to create a music video for it. Otherwise, I can't upload it to a video sharing site.

This is a library of music video "generators", anything that can be recorded along with a music file to produce a music video. Usually, this means a dynamic HTML page with some kind of dynamic visuals.
