Google Apps for Android

Google sieht seine Lizenzvereinbarungen durch Custom Android ROMs verletzt - in der Tat handelt es sich aber um Custom ROMs, die nicht unter einer Open Source Lizenz stehen, sondern von Google entwickelt und gewartet werden - wie Mail, Calendar, Contacts und Youtube. Diese werden zwar in der "offiziellen" Distributin mit Android vertrieben, sind genaugenommen aber nicht teil der Platform.

The Canvas Element in HTML5

The "canvas" tag was first introduced by Apple in WebKit for the <a href="http://www.apple.com/macosx/features/dashboard/">Mac OS X Dashboard</a>

Meanwhile, it is supported by Mozilla, Chrome, Opera. The current state of <canvas> allows to do full 2D operations and animations directly in the browser. Tutorials usually start with boxes and circles, but there are advanced examples that show off "oldschool" demo-effects or even the display of 3D objects and landscapes. The <canvas> element is even supposed to provide a 3D context, that shall allow such transformations. However, this is not yet supported on all popular browsers.
