animated eyes

Find a ralatively square image, and if not square, use gimp or an equivalent image editor to crop it to square. Idealy resize it to match your display (240x240 for round displays), then uoload the image to  https://impressto.ca/bmp_converter.php  Source: https://github.com/impressto/bmp-to-c

If the image was not the correct size, you can resize it in the tool above. Once you save the new c header file, you can save it to your esp32 or arduino source folder and include it in the head. 

Source code for the esp32 is here: https://github.com/impressto/esp_lcd_eyes
