I don'tknow what half those are, modern simplistic.
I've repeatedly found the styling of (apologies in advance) IKEA's "LILLÅSEN" desk caught my eye for being simple and modern, although it's probably not quite as modern as you're after, and also far too small to be practical.
Buuuuut...
Drawing some inspiration from the design of the working surface of that inexpensive sweedish offering, and some from the side table with the triangular frame in your first post, I could see a way to make something quite striking using a fabricated steel frame providing support, clad with timber of your choice, on a "foot" which is either very heavy, or secured to the floor.
See some hasty CAD (no textures, or rendering) of the kind of thought I had using a 300mm lead hemisphere as a foot, and a 800×1600 working surface with 3 off 395×500×55 drawers.

Should be good for a load of about 40kg at the furthest point from the foot, which is more than enough load support for use as a desk; but definately well into "form over function" territory compared to something conventional.
