In my dream last night I was playing guitar. And out of nowhere I busted out a slide. However, this wasn't an ordinary slide. Instead a circle it was a triangle, and it played even better than a regular slide would. Now that I'm awake, I'm thinking.. Would a triangle slide feel/play better on a guitar? Because think of it, you're playing with a smooth surface on the strings.
Btw: I looked all over and couldn't find what I was talking about, but if it has still been created anyway, sorry for wasting your time. It was just a cool idea.
The slide acts as a fret on the top of the string.

Edit: While I've never tried a flat slide, I can't see it working out too well. Now the pointy end of the triangle may.
hahah brilliant! triangle slide!
