watched the vid, very interesting!

A few points of constructive criticism though:
- Try to keep looking at the audience! You seemed to have the tendency to look in the direction of the ground, especially when you'd be walking from one end of the stage to the other. Looking at the audience will make your presentation much more direct (as in directed towards the audience) and help people keep their attention focussed on you!
- Try to breathe through your nose rather than your mouth, inhaling (and exhaling) deeply through the mouth gets picked up by the mic and amplified, and can become like an interference in your speech.

Just my 2 cents hope you can incorporate them in your presentations to make them even better!

Again, want to stress the point I really enjoyed your presentation and found it quite interesting, especially the part about that company, Festo, that used those "novel toys" as you said to devolve back the knowledge into the products they produce, and the subsequent part about how the cerration of the feathers of owls is being employed to make airplanes a lot quieter.
