Set 'em up and make 'em fall.

Dominoes is almost as classic as Lego as far as childhood games are concerned. Not the Dominoes where you have to match the count of those darn dots. I'm talking about the stacking of Dominoes in such a way that they fall in a Slinky-like motion, each falling Domino leading to another falling Domino. Well that was the plan anyway. It didn't always go as planned. After spending what seemed like, or maybe was, hours setting up hundreds of individual Dominoes, keeping the cats and siblings at bay so as not to knock over a critical keystone, I would hold my breath and tap the first brick. All that work either led to an incredible rally that lasted 15 seconds at best, or a dismal failure that lasted maybe 3.

Well, as with all things nowadays, even the Domino rally has come to the web. Drawminos allows you to build a Domino chain in your browser, then see it fall. Unlike the real world, this site lets you make modifications to correct those gaps and misalignments that caused the dismal failures. You can move them around even after they fall to craft a piece of art. You can save your successes or view other's as well.

This site is good for at least few minutes of reminiscing.
