A colleague of mine showed off some really cool stuff with famo.us the other day. Though I’m yet to be convinced as to how code in famo.us might scale to a huge application, I couldn’t resist the temptation to play around with it because it was so freakin cool!
I decided to write something that would give its performance a bit of a test - so the Matrix’s “Digital Rain” seemed like an ideal candidate.
The live demo is here: Digital Rain
Obviously can use quite a few touch-ups and optimizations - for example, currently the size is fixed. But I whipped it up fairly quickly just to get an idea of how to use famo.us. I think cljs/core.async/famo.us could potentially be a lethal combination for certain classes of application.
One interesting thing to notice is each column has a completely independent state. We wait a random amount of time between inserting each character, and then wait an additional random amount of time before starting to timeout-fade the character.
