4ft X 4ft X 18" deep. 3 tracks with a chain lift that delivers about 6 marbles per minute onto the tracks at the top.
I use 1-3/8" glass marbles and all stainless steel. There are 7 spinners on these tracks. 2 large rings, 1 reverse jump-rope spinner, and 4 small rings. They add a nice clink sound and spin around, some fast, some slow when hit by the marbles. The loop d' loop has 5 inversions and ends with an open ended track. The only thing keeping the marbles from rolling right off the end of the track is their back-spin. The back-spin stops the marble quickly and sends it back the way it came.

  • Just a really great rbs. One of the best I've seen. I own #72 that Matt made.  I am jealous of his talent.

  • Thanks CB! ...But, you'll be able to brag about your new desktop, though!

  • i'm serious how much do you want for this? I,m willing to go in the 4 digits

  • Beatiful!

  • how long did it take you to this?

  • i absolutely love your sculptures, if i could afford it i would buy one... for me, the most satisfying bit of this video is the stationary camera at the end, i could watch this sculpture all day x

  • Beautiful...Just Beautiful!!

  • Very nice!

  • I really enjoyed the detailed ramps and the length of the video. Too often it is too short to really appreciate it. Good Job!

  • I saw this video linked from the Yahoo list...Nice work! I really like the way the train of marbles looked going through the horizontal S-curves when viewed from the front of the sculpture.
