Some interesting UI stuff—Namdev
5by5.tv has a button you can turn on so that links open in a new window. (I love this because I open everything in a new tab with the goal of making it take about 30 minutes for Firefox to start up.)
Top: The search field at apple.com when you load the page.
Bottom: The search field once you insert the cursor.
Top: The footer on the already excellently designed Daring Fireball.
Bottom: The Appearance settings on Daring Fireball where you can only change the font-size. I like that this sends the message that changing color or typeface is bullshit and the font-size is most likely the biggest culprit in terms of reading difficulty.
