I first found this video years ago and it completely blew me away. It is such a fantastic example of taking a subject which is completely foreign to most people (the inner workings of a differential) and making it absolutely clear and understandable to anyone. This absolutely belongs in the Explanatorium Hall of Fame.

If you don’t know how a differential works, or even what a differential is, take a look. In less than 10 minutes you will understand the basics completely.

The detailed explanation begins around the 4:00 mark, but don’t skip too quickly or you’ll miss the vintage motorcycle stunting!

Around the Corner


Infographics Gallery

by Connal on January 2, 2010

My wife and I are currently in the middle of a year-long sabbatical where we’re touring the world. You can read all about it on our travel blog: www.adangerousbusiness.com.

As we travel, one of the things I’ve been taking pictures of has been examples of infographics from around the world. I’m defining infographics here loosely as anything from a map to a signpost.

A few samples from the collection are below and you can see the full Flickr set of Infographic Samples here.

Rock Band Drum Kit Fix

by Connal on July 19, 2008

Thanks to some over-enthusiastic drumming I managed to crack two of the plastic pads on my Rock Band drum kit. The kit still worked fine, but because the hard plastic underneath the rubber pad was cracked, the action was completely dead – the stick thudded against the rubber, rather than crisply rebounding. I figured it couldn’t be too hard to fix so I took things apart.

Monopoly Rental Prices

by Connal on July 15, 2008

This little project started when I stumbled on a website of competitive Monopoly tips and strategies. I’ve played Monopoly my entire life, but never once considered employing advanced strategies. The biggest change in my game was the day I passed over the car in favor of the thimble as my token of choice – not only because I decided I wanted something more humble and understated, but also because it allows one to make lisp-based thimble jokes (the thimble of victory, the thimble of eleganth).

Local Mexican Restaurants

by Connal on May 2, 2008

View Larger Map

It’s not specifically infographic, but it does include an interactive map.

Back in January we moved into our new live/work studio in Oakland’s Fruitvale district. It wasn’t a very difficult transition to move from San Francisco’s heavily-Hispanic Mission district into to the also heavily-Hispanic Fruitvale district. What we did find was that we were going to have to re-discover a whole new set of local eateries. As in the Mission, there are Mexican restaurants everywhere and also just like the Mission, you might never walk into some of the best ones unless you had a little secret local knowledge.

Luckily for us the May issue of San Francisco Magazine had an article about local Mexican restaurants, with a suggested must-try specialty for each one. Browse the map below or open up the full-page version, along with text about each restaurant.


In Progress: Poker Sparkline

by Connal on April 24, 2008

A while back, after a particularly frustrating string of online Poker games, where it seemed like I was catching nothing but garbage cards I thought it would be great to be able to go back and look over a game, hand-by-hand, to see how often I caught strong hole cards and when I did catch cards, how often I won with them.

Technically I can already do this. Most of my online playing is done at Full Tilt Poker. One of the cool features of the site is a “Hand History” which records everything done on every hand: What your starting stack is, what your hole cards are, what cards are dealt, how much you bet, what the result is… It even records any online chatting between players. For example, a sample hand looks like this (my screen name is “cabbotage”):

Better Like This?: Neighborhood Map

April 16, 2008

Below are the before and after versions of a map I did a while back as part of a project on neighborhood rehabilitation. The map covers a 5 x 8 block area in Oakland, and displays the 10 different land-use zones that exist in the neighborhood. The original map is roughly accurate down to the […]

The Greatest Weightlifting Diagrams Ever

April 12, 2008

These images, some of the greatest explanatory diagrams ever created, came from Bill Pearl’s Keys to the INNER Universe(his capitalization). I’ve scanned in a handful and uploaded them to this flickr gallery – but if I had enough time I could easily scan the entire book. There are an average of 3 of these diagrams […]

Visualizing Hand Groups in Hold ‘Em

April 7, 2008

In the last few years I’ve developed a huge interest in Poker, and after reading a number of poker theory books, I’ve started experimenting with alternate (and hopefully better) ways of illustrating common poker theory. In this case, the lists which rank the strength of starting hands in the game of Hold ‘Em.
