I'd like to work on this! 😄

@BK1603 Cool, feel free to do so! But I must warn you that I am pretty short on time for the foreseeable future, so it might be quite a while until I get a chance to review this. I won't forget about it though.

As a workaround.
You can do that with timeout.
timeout -t 20 ./ternimal length=100 thickness=1,4,1,0,0 radius=5,10 gradient=0:#666600,0.5:#00ff00,1:#003300ww
