Mac OS X 10.5 'Leopard' is scheduled for imminent release in a few weeks time, but while you wait you can take a look at the new and improved Leopard "Welcome to Mac" message on teh interweb.

The Apple underground is at it once again, with CrunchGear publishing a short collection of Mac OS X welcome messages that show the iterative improvements between each version of the OS.

The collection includes the new and improved Leopard welcome video. The welcome clip is the first thing that greets a user when they launch their new Mac.

The new welcome message seems to prove the increased sophistication of the hotly-anticipated OS when it comes to handling moving images, partially due to major improvements in the systems Core Video handling.

Anyway, while we wait for the OS to ship, we can take a gander at the new welcome screen here.
