The title is not 100% correct because I did not create these tools, but I use them and will use the last one everytime I give a presentation:

1. PowerPoint presenter view
In powerpoint 2007 there is a feature that enables you to display the presentation on the beamer and on your personal monitor you are able to see your notes, the time you are presenting and wat the next slides will be. It is a very nice feature and I recommend everyone to start using it.

Powerpoint 2007, under Slide Show there is a checkbox Use Presenter View, specify the correct output settings and hit F5.

2. ZOOMIT

This tool makes it much easier to zoom in on your screen, very handy when showing code examples or small settings dialogs.

3. A wireless mouse or presenter stick
You can walk around so you are more energetic. don't stay hidden behind your laptop. use the wireless mouse or other tools to navigate to the next slide.

4. Demo code shoud be ready before the presentation.
Nothing is so boring as someone who is developping his code online. the audience wants to know how it is done and what the result is. So create the examples upfront and put them somewhere safe.I used to put them in visual studio toolbox or in a content editor webpart in the webpart gallery but at techdays, Gill showed me something far more interesting.(see 5)
