Exercises in secondary dynamic effects

The looping wave motion is more difficult to create than I expected.
Two of the earlier mistakes include a standing wave and a “smoke” that moves up and down.

After watching a candle fire extinguished by wind, I tried to capture the essence the memory via drawing the simplest possible animation.
Without looping, it is easier to create a jumpy fire followed by a rising and distinguishing smoke.

Decomposition

The disintegration of a dead body is its reintegration back to the nature, and inspires me to decompose my sketching.

Mamba graduation wine bottle

This is my first graphic design, to celebrate the graduation of my last HKU PhD student who derived her nickname from the black mamba.
(I managed to help her publishing top papers but not converting her from LAL to GSW.)

The neighborhood black cat often came to visit.
The sketch is a composition based on two photographs.

Drawing a composition of evening sun and moon

This composition is astronomically implausible (unless there are multiple suns above the horizon) but I felt like doing it after seeing the evening sun and moon at opposite ends of the sky.

A spider on a flower

A spider, resting on a lamp shade, scurried away after being gently poked by me to see if it was still alive.

This exercise aimed to reproduce my impression of its movement, but over a flower as captured by an earlier photograph of another spider instead of the lamp shade.

I drew the flower and the spider in multiple layers via Fresco, exported the pdf file to Illustrator to animate the spider via puppet warp, and assembled the final video from the individual spider layers/frames along with the flower.

Even with puppet warp, the authoring process still involved tedious manual repetitions, which can be alleviated by autocomplete.

End of consumer toilet paper shortage?

Just a few weeks ago the US was suffering from a shortage of consumer toilet papers, so I was a bit surprised to see a pack of unopened toilet papers marked as free on top of a garbage pile while walking in the neighborhood on Sunday evening.
I wonder if that is a sign that the toilet paper production has finally ramped up?

I once saw a groundhog poking its head out of its mound in a nearby county park.
This one was drawn via a reference photo.
