Deeper and deeper

One mustn't look at the abyss, because there is at the bottom an inexpressible charm which attracts us.
[Gustave Flaubert]

This generative animation, with a hint of interactivity, represents an endless descent, now slow, now faster, a glimmer of light, a flash... mixed sensations.
Can you hear the sound of the fall?
I could have added it, but it's more interesting to imagine it.
