Lately I've been on a CSS3 Animations/HTML5 audio jag. It's just so much fun, I've been working hard to share my techniques with everyone:

• 24 Ways posted my article about Flashless Animation
• Check out my slides from my CSS Dev Conf talk "Animated Music Videos with CSS Animations and HTML5 Audio"

Additionally, you can check out some of the live demos I've done directly:

• NyanTuna
• Final "Candy Candy" animation
• "Coming Soon" animation
• "Cat in Byakkoya" parallax animation

Hope you get inspired. Please, show me what you come up with!
