Generate new patterns for Peter that are not gratings but have something like an individual bar.
- Make them 2 rows high and 12 columns wide.
- Greyscale 4-bit.
- Small pattern with few frames. Perhaps, all greyscale frame, then frame with a single bar, then all greyscale, then a frame with a single bar at 180 degrees from the bar in frame 2.
Ideally, convert the .pat file to a binary format that can be read in in python.
