Something interesting just popped up on YouTube.
The Sky High City of SteamPuff - Episode 1
Welcome to the SKY HIGH CITY OF STEAMPUFF, a floating clockwork continent lost amidst the clouds, where anything and everything is driven by the power of steam. But when brilliant steam-smith Hephaestus Von Toot is kidnapped by an unseen foe, it's up to his son Victor (and his squadron of steam-powered friends) to not only track him down, but defeat the powerful forces that would threaten to drop his city from the sky.
I recommend watching this in full-screen mode.
Looks like some nifty animation, enough steampunk to satisfy the small boy in any of us, and prospects for an interesting series. It may be worth keeping an eye open for the next episode.
