There are such cool designs that it's a shame nobody nowadays tries anything similar.

You would be surprised :)

There's a company called WonderWorks that embodies this style

These existed?

There's one there that's a parking lot that ripples and the store is under the ripples, and it's only shown as a model. I'm guessing that one was never built, because it looks really dangerous and confusing for drivers.

I remember the one in Sacramento, with the corner that slid in and out. I didn't know there were others at the time, nor did I realize how unusual an architectural experiment it really was.
