I am working on an air and noise pollution sensor called Street Sense that uses LittlevGL to drive the graphics display. All the coding is done in MicroPython. I use the MicroPython binding by @amirgon (Big thanks Amir!).

Here is a project log entry describing how LittlevGL came to my rescue when I was switching to a MicroPython port that lacked a strong graphics library for TFT displays.

The project was recently featured by the Canadian public broadcaster called the CBC:

The interviewer really liked the decibel meter screen. I used a huge 120 pt font for the measurement and the screen changes to a red background when the sound reading exceeds 85 dbA. Very effective to get the attention of an interviewer.
