   That's pretty much how the oscilloscope in this is done. I animated the parameters using matinee. http://www.vimeo.com/22880192 However I used a clamped sine wave instead of the horizontal line texture. Good tutorial.

   wont multiplying the sine just increase the amplitude? dont you need to add to it in order to move it upward, getting it out of the -1 - 1 range?

   Fun material. FYI there's an error in your math. The sine function always gives a value between -1 and 1 no matter the input. It's part of the nature of what the sine is. To get amplitudes greater than 1 you'll need to multiply the output of the sine by a number greater than 1. The wave look of the function occurs as an…

   Haha, awesome. Yeah, I guess it's pretty straight forwards stuff but it did take a me a couple of hours to get it working exactly right. It was actually that EXACT video, two days ago, that inspired me to try this out. :D Thanks for the compliment. I'm thinking about doing a follow on mini-tut about animating MICs in…

   At first, I was like "pfft, whatever, pan a gradient into uvs", but then after seeing all the parameters in the video I thought it was neat. It's funny, a while back I made a snakes particle that used a similar technique.

    :) You've done a great job. Don't get me wrong. I like the effort you put in and the material does do its job. Kudos for that. I'm just one of those who feels that a deeper understanding of what you're doing can go a long way toward creativity and productivity.. and your minor trig error actually inspired me to go make my…
