Oslo is going for something very simple compared to the high-tech stage design and visual effects of Helsinki, Belgrade and Moscow.
The main effects accompanying each performance are light displays behind and on-stage as well as props such as string beads or curtains which are lowered from above. Variation is added by stage props brought by each performer from their home countries to the stage.
Being a much smaller host city in a much smaller country in quiet Scandinavia, simplicity also shows in other parts of the organisation of ESC 2010. Journalist are encouraged to bring their own laptops as there are few computers provided in the Media Centre. Missing also is the tight and advanced security controls of Moscow: in Oslo at the entrances to the Media Centre and Telenor Arena a few chatty security staff use hand held scanners to authenticate the security passes of each visitor. The process could cause a queue during rush periods but one of the interesting things about Oslo in general is that folks do seem to have time to spare, which can also be a nice thing.
