This droideka is a modification of the old version of the droideka in the set also including Obi-wan Kenobi.
About this creation
The third eye was attached onto the stud under the droid body. The pistols are DC-17's (dark grey) with binoculars attached onto the ends. Although the stud holding the third lever looks a bit awkward, I think it still looks pretty good. As you can see in the bottom view, I also added a circular, rounded 2x2 brick to the bottom of the frame that holds the legs.
The photo is a bit dark. You should either use a large apeture or fix it on the computer. For small creations, you should use blank printer. I emailed you the pictures that I fixed with exposure and stuff. If you come to my house, I can show you. Also, you should post your droid turret. Please comment on creations!
