A couple of events taking place now Megapolis2022 (via) and Hernesaari scheme proposals (via).
Megapolis 2022 is an urban environmental festival and seems like a growing event, the premise is right, that our current environmental problems will be solved in the cities. On Saturday 13th October, there will be a debate about the role of the consumer in this.
With the Hernesaari scheme the City of Helsinki Planning Department is opening up a little to the outside world. Until 21.10.2007 you can look at the different scheme proposals from Anttila & Rusanen, Brunow & Manula, and Helin & Co and comment on them. Image above from Antilla & Rusanen scheme which I really like as it adds a public space of grass and beach with water on either side.
