Hehe, I'd record a vid but it takes so many tries!
I sort of [spoiler]left one cube bouncing in floor portals in front of the laser to get the other round the corners and onto the button. Then I placed one portal close to the button, one next to the elevator, hit the button and jumped through onto the elevator. At the top of the elevator I jumped into a portal, and other other side grabbed one cube each time, bringing them back up onto the platform. From there I placed a portal juust in front of where each cube needed to be, and one by one jumped down with the cube, placed it, and jumped bacck up to grab the other...[/spoiler]. Then I skipped out the door 
Would love to know what was intended!
