It was one sheet per circle. I can't find my plans for the circles but I think it was around 9ft in diameter and about 8 sections. I utilized every bit of the 4X8 plywood to make one circle. The geometry to find the circumference is pie x Diameter.
We used an old bike wheel and gears to get the right speed for the tunnel. To see the finished product go to search my ID kylekayj or go to "vortex tunnel halloween 2008"
The Diameter was 9 feet the max to fit in the garage and it was 16 feet long (two 8 foot sections) The rings were cut out of 3 4x8 pieces of paticle board. I cut the rings in to 7 sections and then doubled them up to create the circle. Had to break open the high school geometry for that. The rings are conected using 1x2 and they sat on some handtruck wheel rims that we mounted on some 2x4. Costs were small because we used mostly scrap wood. The Bridge was 18 feet long and cost the most.
That looks great! If you made two and placed them in front of each other, you could reverse the direction of one and really make people dizzy!

hey man, how hard was it to find the arc needed to make the circle? how many sheets of 4x8 plywood did you use?
