Have you seen V&A Steamworks Crazy Arms?
I have always loved minifigs and customizing.
Although if you wanted a more dynamic arm position, you are a somewhat restricted or in need of jury rigging some flex tubing to get the job done.
I just finished a batch of these custom arms and have them now available for folks to use. The replacement ‘Crazy Arms’ are highly engineered in that they accept the existing hands perfectly ( they click right in ) and POP in the existing torsos with a nice click. They can easily be swapped and changed out.
They come in Black, Cocoa, and Eggshell White.
I may also run some additional custom colors soon.
Details on ordering a set for yourself are on his Photostream
Unless you are going to Bricks by the Bay. ;)
Guy gave me a whole set of both his Stovepipe Hats and his Crazy Arms that will be available at my booth for sale :)
Hats will be $3 and a pair of Crazy Arms is $5. Come on by and get some for yourself.
