the sparks of passion reentered the stadium in this segment where the largest and tallest olympic rings for the opening ceremonies would be created. acrobats could be seen maneuvering on three ring shaped frames floating up and down along four lattice columns on the opposite end of the stadium to the stage and the mosh pit. dancers in red unitards below gyrated to pulsing beats as the theme of passion returned for this segment of the program. while the acrobats descended to the ground, two additional ring shaped frames were raised. the five circular frames were flipped vertically revealing the five olympic rings shimmering in light. the rings were then illuminated in the olympic colours and the structure was lit up in fireworks. the black ring in the centre of the symbol was substituted with white since it is impossible to produce black light.
