This was a fun thing I made to demonstrate different movements of clocks. Check out this proejct for more pen clocks (This one is better) https://scratch.mit.edu/projects/500952163/ Top Left is Regular, Top Right is Smooth, on the Bottom Left the second hand is rounded to the nearest 5 seconds, and finally the Bottom Right is backwards. The Bottom two are pretty useless, but fun to make and look at anyway.
It is all 100% Pen. All the times are taken from the correct time. (The bottom two clocks may be somewhat hard to read though.) The clocks animation in general may be useful for making measuring devices like speedometers etc. (With Credit, of course.)
