This is Catastropha, one of the the largest ball machine I have constructed to date. It has 11 lifts and 17 paths.
The lifts are:

• Wheel lift with holes
• Alternator lift
• Double helix lift
• Ring lift
• Inverted chainsaw lift
• Small arm lift
• Pump list
• Mouse wheel lift
• Inverted motorized single helix lift
• Mill/Wheel lift
• Stair lift

Even thought it might won't seem at the first look, there is equality on Catastropha. The table below will show you.

Path number	Network 1	Network 2	Network 3
1	1/3
2			1/6
3			1/6
4		1/3
5	1/4
6			1/4
7		1/4
8			1/4
9		1/6
11	1/6
12	1/6
13		1/6
14		1/12
15	1/12
16			1/12
17			1/12
Sum it all up:	(1/3)+(1/4)+(1/6)+(1/6)+(1/12)=(4/12)+(3/12)+(2/12)+(2/12)+(1/12)=12/12=1	(1/3)+(1/4)+(1/6)+(1/6)+(1/12)=(4/12)+(3/12)+(2/12)+(2/12)+(1/12)=12/12=1	(1/6)+(1/6)+(1/4)+(1/4)+(1/12)+(1/12)=(2/12)+(2/12)+(3/12)+(3/12)+(1/12)+(1/12)=12/12=1

You might wonder why path 10 isn't in the table, that's because that it comes is so rare. To calculate that: It just happens when the four balls leave path eight, as it have to be four we have to do (1/4)*(1/4)=(1/16). And now only one of the balls go down that track so (1/16)*(1/4)=(1/64).
