Apologies in advance to iOS users for pointing to a Flash-only resource, but Cary and Michael Huang’s “The Scale of the Universe” interactive page on NASA’s Astronomy Picture of the Day site is a fascinating update to the classic “Powers of Ten” video created in the 1960s by designers Charles and Ray Eames. We were particularly amused to see Boeing’s Everett, Washington aircraft plant (on the scale of Vatican City) and the virtual Minecraft world (larger than Neptune). follow link
Mighty Mouse as Application Switcher
Looking for an easier way to switch between multiple applications? Within Keyboard and Mouse Preferences under System Preferences, you can configure the scroll wheel to act as an Application Switcher. Press the scroll button to bring up Application Switcher, scroll to toggle to the application you want, and hit the scroll button again to switch. You can also double-click the scroll button to quickly switch to the previously active application.
