Very fun. I found bug(?) The ball slip through when confined to a very small square.

there are some other bugs in there, too i.e. try if you manager to let the ball fall exactly at one of the end the lines (it's NaN error ...)

The goal is the one you make up for yourself, but basically get the dot into the square! Again and again and again!

Loosely based on http://annotated-code.maryrosecook.com/circles-bouncing-off-... which was on HN a few months ago.

If you find a bug or want to improve it, you are welcome! If you want to "steal" the code and make something complete different with it, just do it. Want to make a native app, sell it for 99c and get a millionaire, go ahead.

note: LSD is the abbrev. for line square dot

With no limit on the length and number of lines that can be drawn, making the ball touch the square is just a process of drawing successively smaller triangles.

that's why there is an average counter on the right hand side top, you can play agains yourself (aim to get a better average over time)

Addictive.

it's called LSD (even though some people now told me that LSD isn't addictive)
