Don't get me wrong, I don't think I'm the trend setter (I don't get enough views for that). Everyone was probably thinking and drawing the same thing I was at the time and I was probably just the first to get it on the internet, but still... I find this pret-ty awesome. Because object head Wheatley is my favorite Wheatley (except for the original) and the cast of my "Portal West" is (for the most part) object heads.
Even if I was the first to do the object head Wheatley thing, though, someone did a companion cube/ pyramid head a ways back (2007) which was [also] ragingly cool.
If I'm wrong about any of this, please let me know (nicely). I don't even want to reject credit that isn't mine to reject.
Edit: found an earlier version from April 18th, so I am definitely not the perpetrator. I'm just one of the many people who came up with the same awesome idea.
