Thanks to Peter Murray from Apple for hosting the session at Mt Lawley Senior High School in Perth, Western Australia today. It is great to see so many educators interested in the learning that can occur through the communicative and creative potential of Macs.
Here are links to the tools I did a show n’ tell on today - I’d just like to remind you that some of them are still in beta 
Pixelmator, the beautifully designed, easy-to-use, fast and powerful image editor for Mac OS X has everything you need to create, edit and enhance your images. (Update: this software is in locked beta - thanks Brett and Steve)
Pixen is an innovative graphics editor for the Mac. Pixen is like a very powerful MSPaint or a simpler, more agile Photoshop. And best of all, it’s Free!
Kahootz is an eduational Software application that allows students aged 5-18 to create their own 3d content. Share designs with schools around the world.
PhotoPresenter offers many gorgeous styles to create animated slideshows with amazing effects.
Jing: the concept of Jing is the always-ready program that instantly captures and shares images and video…from your computer to anywhere.
Virtue Desktops allows you to achieve similar to what Apple Spaces will do when Leopard arrives in October.
Skitch is the Internet age’s Camera and it Rocks! The best screenshot tool in the world from the team that brought you ComicLife.
Pixadex is to icons, what Apple’s iPhoto is to images. Pixadex lets you import, organize and search huge numbers of icons quickly and easily.
MacSaber uses your Mac’s sudden motion sensor to detect movements, fast and slow. As you move your laptop, MacSaber plays varying levels of Light Saber sound effects, from a waving sound to exciting saber crashes. 
If you’d like a beta invite to test Skitch contact me here:

A great list of apps… May I add Snapz Pro for screen captures etc… Used it recently for a lesson I did with my students that was captured then added as a podcast. An overview of this is on my website under the latest podcast.
Can I also suggest school-house… created by a student for students to keep track of school work etc.
Cheers,
Brett
Just letting you know that Pixelmator is out of Beta is no longer available until it is for sale.
For virtualisation, I just wanted to add Crossover http://www.codeweavers.com/products/cxmac/ which is probably the most convenient way of using say Ms Outlook rather than flicking to Parallels. It’s up to version 6.1 now and has a lot of software in its Windows database that you can use. I thought Apple might buy them out and put it in Leopard.

I would like to suggest iShowU as an alternative to Snapz Pro as it provides a lot of control over compression settings for the movie you create.
School-House is very good. People may be interested in looking at Journier as an information manager. It has a fantastic set of features and links up with the iLife media, can add voice recording, video and photos. I use it to capture web content when researching - just print to pdf and send to Jounier.
Other applications worth a look are iGTD and Ganttproject.
Cheers,
Kyrne
