I reported earlier on the artwork that will be in place for the 2008 Olympics, search for “Strebelle” in this blog.
As the groups of sculptures are pretty tall – up to 20 m – it was interesting to have an idea of the actual size within the Olympic Park. Solution: balloons, one for the first group (red), one for the average height (multi-color) and one for the maximum height (green).
The Strebelle technical team made the experiment with its Beijing counterpart on 1 September.

See some of the pics with different views on the balloons, the Olympic Weather Monitoring Station, the technical team and how the trees are coming along in the Park.
Hopefully the weather station will be able to report better API than in the past days.
