Impression of an evening lamp over an utility cottage

Filed under: Imaginary,Real — liyiwei @ 10:42 pm

I painted from impression the scene of this little cottage, built around utility equipments, lit by a nearby yellow lamp after dark.
(For more background information, I recommend this.)

Stable diffusion can work well for this case.

I dreamed about making an U-turn on my bike over the side of a school bus

This is a dream I had over a year ago about taking a U-turn on my bike over the side of a school bus in a junction of the University avenue at Stanford university. (The dream might relate to my once getting stopped by a campus police for over-speeding on a bike.)
I have been having difficulty sketching what I saw in my dream, and finally decided to do the best I could with some visual references (bike turn, school bus).

Stable diffusion seems to have difficulty with such out-of-sample case.

This is a light-hearted experiment to see if deep learning has somehow spotted Satoshi Nakamoto in the training data and could shed light on their real identity.

Green beetle

Filed under: Real — liyiwei @ 5:38 pm

The body of this green beetle is too small for me to see the details without amplifying glasses, so I painted a coarse version and let stable diffusion come up with the details. The results are more vivid beetles with colors and shapes that roughly match my drawing, but completely different types of beetles.

I experimented with stable diffusion over some of my own manual drawings and here are the results.

Natural authoring modalities

Filed under: Real — liyiwei @ 11:32 am

The technology has finally reached the point for which content can start to be authored via natural language and gesture (including drawing) instead of unnatural WIMP (windows, icons, menus, pointer).
The state of art (e.g., DALL-E-2) can already be part of the content creation toolbox, and future advances may soon obsolete legacy tools.
