Pecha Kucha
I tried to listen to Fertile Voids at first, but after the first few minutes I got bored of barely understanding her, and the bland presentation made me doze off. Since I didn't finish that presentation, I decided to listen to another one so I'd have something to write about.
My second choice was Tools for Design. It intrigued me way more than the other, his voice kept you awake and wasn't monotone like the other. Adding to his great speaking voice, the way he setup his presentation with all of his eye-popping visuals was extraordinary. Although I didn't understand half of the engineering examples he was talking about, his presentation was still excellent.
