Never heard of "Shepard Tones" before, so thanks for educating me
Now that I know, though, having watched the 8dio video I think I would prefer to have a go myself... I have been having lots of fun with sound design lately...

@TheSteven, that sample cracked me up haha... I could certainly make something interesting out of that
