Calvetica is an iPhone application by Mysterious Trousers (who also make Dialvetica). It is a calendar application that aims to provide users with a clean, minimalist interface with very little UI chrome, and provide a fast and functional experience.
John Gruber of Daring Fireball said of the app:
$2.99 calendar app for the iPhone and iPod Touch, with an emphasis on fast, convenient event creation and a very crisp, stylish UI design. Behind the scenes, itβs built on the iOS system level calendaring APIs, so it syncs perfectly with the built-in Calendar app.
There are two themes available, “Patented Calvetica Red” (the light grey theme) and “Black Is The New Fuschia” (pictured below).

1px Clock is an iPhone app that shows time, ticking away one pixel per second.
Each square is built up of 60 rows of 60 pixels: one for each second. As such, one square represents one hour, and the total of 24 blocks make up 1 day.
1px Clock was developed by Japanese web design firm E-Bird, and is available as a 6×4 version and a 2×12 version. Download the 1px Clock here (free!).
No iPhone? It’s also downloable as a screensaver. (Thx, Derek!)

A great alternative to numerical clocks is this worded clock by Biegert & Funk.
Called QlockTwo, this clock tells the time using words highlighted by LEDs. It is available in numerous colours and languages.
I like how the smooth design and structured typographic grid compliment the illuminated words and make it stand out.
You can purchase the QlockTwo in various colours and languages via Biegert & Funk’s online store.
And there’s also an iPhone application available!
