From the Speech text:
Contemporary architecture has returned to two of the most radical formal preoccupations of the early Modern Movement: the aspiration to transparency and weightlessness on the one hand, overcoming bounded space, and the Expressionist aspiration, largely unrealized in its time, to an architecture of colored space... Today the qualities of transparency and weightlessness scarcely seem radical to us, but the concept of space expressively altered through color has only recently become a subject of investigation.
Architect: Alejandro Muñoz Miranda, Granada
