Spot On - Locative media seminar panelist Mika Raento says there have been enough prototypes and media arts projects for now and it's time to see real services using location data. Anybody can put media on the map with a mobile device or on the desktop. Now it's a question of actually doing it. Another Jaiku alumni Teemu Kurppa sees location data as an ingredient, but not necessary a starting point of a service. Your city is a game, says Mikko Hämäläinen, (@miksa) one of the co-founders of Grey Area Labs specialiced in location-based alternate reality gaming.
