LISSAJOUS FIGURE VID

browsing the really cool EXPERIMENTALIST ANONYMOUS BLOG, i found this great video of a LISSAJOUS FIGURE portrayed on an oscilloscope. from what i gather, a lissajous figure can be generated using a scope by injecting one wave ionto the x axis, and another onto the y axis. summing them together, you get this 3D effect. the maker of the video put the left channel through the x axis, and the right through the y, all the while tweaking multiple effects. as i finally picked up a scope recently, i find this sort of thing fascinating. unfortunately, the cheapo 40 dollar scope i got only has a single channel, so you won't be seeing any lissajous figures from me in the near future.
