### Blue Balls Machine

The Blue Balls Machine is a wonderful Rube Goldberg contraption that serves no purpose except to move, well, blue balls from one place to another. It's not a game, and not exactly a work of art; I don't know what I'd call it, exactly, except that it's mesmerising.

A quick look at how it's done reveals that the whole thing is one large (2.4MB) animated GIF, which is impressive enough by itself, but it's even more impressive when you realise that (a) it tiles (try resizing your browser window as big as it will go), and (b) the movement of the balls wraps around the image like asteriods in the old arcade game. The effect is to make a seamless, infinitely big machine, and if you can look long and close enough to see where every ball starts and ends up, then I don't believe you. (Pop quiz: how many balls are there?)

I think all balls are eventually annhialated by the laser, but I can't for the life of me work out where they're created…

2. A nice contradiction here: symbols of constraint (marble race $\to$ treadmill $\to$ rat-race) from someone leading a sufficiently untrammelled existence to have time to create such a delightful, whimsical folly.

Wow, it's bloody amazing. I wasted about 10 minutes just staring at it.

P.S a few balls just go around in circles…

1. I didn't know about the Youre [sic] the man dog genre until I saw this. It seems head and shoulders above the typical examples; altogether in a class of its own. (The Wikipedia link doesn't work for some reason. Typing YTMND into Wikipedia's search box will take you to the relevant page and the same URL!)

2. The Blue Balls Machine tiles the plane with rectangles. Can cascading style sheets cope with more complicated tessellations, even with Penrose tilings? Here are some elegant examples.

Now I know what (another) god must feel like :) There is a quite a bit of creation/destruction going on though.

The balls are created right of the laser that destroys them. Simple.

I see several balls that never leave the system and 3 places where they are destroyed (burning in the test tube, into the iris, and the laser gun) but I still don’t see where they are created,..the light bars near the laser gun are transmat/teleportation beams, so thats the same ball moving through 2 beams.

what I really can’t believe is how badly I want to know now that I’ve looked at this for like 10 minutes solid

And then as soon as I posted I saw it lol right above the burning test tube there’s a box that creates the balls (unless its a condenser for the “ball vapor” created below, but if that were the case I’d imagine it would be DIRECTLY above as opposed to being off to the left a bit..

whew,..I feel better now

This is a closed loop, this image http://content.ytmnd.com/content/e/0/3/e035a08e616468d1b0500bc12dcc11e9.gif is repeated to all sides.
If a ball falls out to the bottom, it falls back in from the top, the same with left and right, that way there can’t be any balls destroyed, they’re simply moved to another area of that picture.
