The SciFi Channel's SciFi.com & Dvice, along with with Make Magazine, have announced a MAKE A CYLON contest.
Tricia Helfer and Grace Park will judge all entries. Looks like you can build either a humanoid or toaster-style cylon or, if you prefer, other objects from the BSGverse. Winning entries will get prizes and be featured on the Sci Fi Channel.
Get the details here from Make's blog.
