Via Make Magazine, photographs of a beautifully fabricated orrery, based on Ferguson's Mechanical Paradox. Not a paradox at all, but an elegant arrangement of slightly different ratios in gears that appear to be identical:

Spent the afternoon baking cookies for the Burney Elementary PTA, scheduled for delivery on the afternoon of 22 Oct 2009.
Was supposed to bake 4 dozen. Got sizing wrong, ended up with about 8 dozen. oops. Hopefully we'll only eat 2-3 dozen before they go out.
Today, John Sircusa re-tweeted a matching set of links from Devin Sanera on the placement of the movement sensor underneath the Apple Magic Mouse and prior research on the placement of motion sensors of mice in general.
Jonathan Hedley writes in, Why are mouse sensors in the middle of the mouse?:
"In a GUI, the mouse controlling the cursor is the fundamental link between the user and the computer. A strong connection is created for the user when the mouse performs well. The emotional attachment created between operator and system is strongest when the system does precisely what the operator requests. Imprecise controls make the operator feel that they are not in control: and so there’s a compelling case to get the design of the mouse right."
"...[most important of all], was the location of the mouse ball."
Too, fucking, right. Possibly one of the biggest overlooked issues with human computer interfaces in the last 20 years.
