A week or so ago, I stumbled across a blog entry that mentioned some nice accessories, one being a click of high heels to replace the standard clump-clump of walking in SL. I left the page up, promising myself I'd return later, grab the location, and get the sound... but things happened, and I couldn't find that web page again!
So... once again I learn to bookmark things right away, and--if someone could point me at that sound, I'd be in your debt.
UPDATE: Many thanks to bcwhittle for his comment! The place to go is Jezebel's, Nyokoland at Baker (138, 148, 39), and it's in a free box that I guess was once labeled "slutty stuff" but is now labeled "sexy stuff". You attach one sound to each leg; beware of other things you might have attached there--I had to move a walk animation override....
...and that done, I proudly took my first walk with clicking heels--on sand, to visit a nearby friend, and clicking all the way... sigh. My friend suggests that Pele does something to the sand near her temple. :)
P.S. I was going to title this entry "The Low Spark of High-Heeled Boys," but decided on what I thought a more apt quote.
