PopcornTime's loading animation
« on: May 19, 2019, 07:41:45 pm »
I guess you can say I have a thing for loading animations, as this is not the first time I post one of these and it's likely far from the last. The thing is, we stare at these so often and for so long through the day that one can't help but wonder "can I code that?", especially as designers become more and more creative on those -- their goal is to entertain us after all, right?

This one is inspired by the one you can see if you use PopcornTime. Hit space to start the fake loading process to see how it represents the current percentage. Images included in the code, so no extra downloads required.

    Pete, That was a salty comment.  Really cheesy.  It was a margarine, lackluster attempt to be corny, Pops.

    Hi Fellippe
    very fine this Popcorn...

    I like those with chocolate!
