This writer is still playing a little catch up after having been absent these past couple of weeks. First up are the images and information we've been eagerly awaiting since the start of the month: the unveiled plans for UNStudio's and Zaha Hadid's temporary Burnham Pavilions here in Chicago. Dezeen has a handful of great images for each, as well as some write ups about each exhibit (lots on UN, but not so much from Hadid). Here's a bit explaining Zaha's space egg:

The structure will trigger the visitor's intellectual curiosity whilst an intensification of public life around and within the pavilion supports the idea of public discourse.

New formal concepts will meet the memory of bold historic urban planning. Superimpositions of spatial structures with hidden traces of Burnham's organizational systems and architectural representations create unexpected results. By using methods of overlaying, complexity is build up and inscribed in the structure.

Doesn't that just explain it all?
