Example of a slowly beating heart:
sudo %s -s1 -m5 " :heart2: :HEART2:"
-m 9 "Smooth"
-m 10 "Rotate"
These modes are mentioned in the BMP Badge software.
Text is shown static, or sometimes (longer texts?) not shown at all.
One significant difference is: The text of the first message stays visible after
upload, even if the USB cable remains connected.
(No "rotation" or "smoothing"(?) effect can be expected, though)
