<DIV><FONT size=2>Hmmmm, this is prolly really eccentric and weird, but i
thought i'd make a comment</FONT></DIV>
<DIV><FONT size=2>to synth-diy about it anyway.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>I just got up and opened the curtains to my bedroom, and i
looked through the fly</FONT></DIV>
<DIV><FONT size=2>screen. About 2 feet away from the fly screen is another
screen / blind (shade cloth,</FONT></DIV>
<DIV><FONT size=2>you can see through it) Anyway, you see this "beating" effect
of the 2 grids cancelling</FONT></DIV>
<DIV><FONT size=2>and reinforcing difference patterns (if i remember my yr 11
physics, Newton's rings?!).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Well, I figured I was looking at a really complex filter. The
closest filter i could think of</FONT></DIV>
<DIV><FONT size=2>that might have a similar characteristic (if u could even
compare light and audio filters!)</FONT></DIV>
<DIV><FONT size=2>to a comb filter. Depending on the angle you look at the
screen, and how close you are,</FONT></DIV>
<DIV><FONT size=2>all manor of crazy patterns are created before your
eyes!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>I wanna know what this would sound like dammit!!!!!
