Here they are! The twenty-two fabulous rings made for the Ring a Week kinetic challenge. I hope I didn't miss anyone. Many made videos of their rings in action, I've linked to those on flickr.

Ship's Log Pirate Ringcopper, brass, silver, Kyanite, feather, cork, paper, leather
"All the captain needs, in a portable, battery free, finger top model. Features - swivel desk for any orientation (suggested use on non-dominant hand). Attached inkwell. Attached, replaceable quill. Leather bound log book with decorated endpapers. Genuine blue Kyanite stone. Engraved 'Ship's Log' and 'Respect the Sea'." The minute I found this little chair at a second hand shop I knew what I wanted to do with it. I even knew I wanted it to rock so when Tomi named the kinetic challenge I was so excited and a little nervous because I didn't know how I was going to do it. I thought about it for weeks and then the day before yesterday after I'd cut out the base and soldered the 3x1mm wire around it, the rest of the mechanism came to me. I was still nervous though and tried to use hard solder for the base and it just wouldn't work for me so I went to medium and for the shank, half jump rings and the 18 gauge wire I attached to the sides, I used easy, crossing my fingers that it wouldn't fall apart. It was definitely a challenge!" Catherine's video is here.
Laura M (Zoewyn)Laura wrote, "The coil limits the movement, and also helps a bit getting all three beads to move since one sort of pushes the rest. But they also just flop around."
citizen.objects Prayer Wheel
"For the kinetic challenge this week, I have fabricated a mini Prayer Wheel. Except for the chain, this piece is made entirely out of antique cuckoo clock parts. 'Handle' is drill press lathed by hand and pressure fitted into the ring shank so it is removable. There is indeed a tiny prayer etched on copper inside the wheel. ***om mani padme hum****" The video is here.
Stacey Johnson (stayseas2001)Stacey says, "The top cage spins around. Band is PMC and sterling insert, cage is sterling and brass with a lampworked bead and pearl inside. The top rotates on brass tubing which is fitted on a long sterling wire attached to the band."

I used cardboard from biscuit box, wire, paper masking tape, plastic part from the top of a pen, and a metal part I found in a drawer that was suitable for this ring....." The video for this ring is here. 
Rae the SmithySpinning Planetary NebulaeRae wrote, "I was inspired a while back by the beautiful Hubble images I saw while visiting the Griffith Observatory. I loved the way the light refracted in a web like manner while simultaneously creating a geometric shape. It was also made as a memorial to Hubble which is sadly being retired." You can see her video here.

Joan FurillaJoan says, "This fine silver ring is for the kinetic challenge this week. The bead and the star motif beneath it both spin. The idea for this ring evolved into a moon lander levitating over a cratered base. I was actually going for a more dark grey patina but when these really wild blues and hot pinks popped I stopped it! Too pretty to lose."
