Those of you with arachnophobia may want to turn away from your monitors. This enormous inflatable spider puppet was built by UK artist Tim Davies for street and carnival performances. Details are still scarce on its inner workings or controls but Davies mentions that the legs are "air-powered." [TD Artwork via Technabob]
I was thinking "Macy's Day Parade" when I read, "street and carnival performances"...I was wondering how he was going to do that with the thing plugged into the wall (see the power cord and yellow reel?)...then I realized he probably means he'll do stationary performances. Der. Less tripping = better performance.
At least that means it's not just "air-powered" but has a pretty hefty need for electricity too...so electric powered hydraulics maybe?
