Same as the original but with c.style='image-rendering:pixelated' to look better and the same size

The effect of blurred reflections with misty and swampy bottom is given by +a**9*i. Without this the image becomes cleaner.

dweet stealer - choose and run another dweet

u/metamero

click on canvas to run selected dweet
u/BirdsTweetCodersDweet

Seems to me like you also need to scroll down and back up again (to pause the dweet and resume it) for it to run, after clicking on the canvas. Chrome {whatever the latest version is} on Elementary OS {also latest}.
u/BirdsTweetCodersDweet

Cool stuff though :P
u/metamero

@BirdsTweetCodersDweet thanks! yes, I couldn't figure a way to call playDemo() after dweet transition/reload (seems timers are also reset). so it'll need to get this "play" message from server when scrolling back. (made in chrome/windows and tested on firefox; same thing on scrolling, but mouse wheel event return different values on firefox)
u/katkip

Awesome
