Jukka Mäki: Green Curl, Blue Curl, 1993. Photo: HAM/Hanna Pursiainen. Green Curl, Blue Curl Artist Jukka Mäki Helsinki Vocational College, Savonkatu 4, 00520 Helsinki Indoor Sculpture Limited access: the work is available to view for the users of the premises only. Jukka Mäki (b. 1956, Kuusankoski) has created two large reliefs, Green Curl and Blue Curl, on the wall of the Helsinki Vocational College, Savonkatu facility’s stairwell. Their material – ceramic mosaic – and the height of the space underline the decorative impact of the reliefs. The swirl shape in the upper part of Green Curl descends in a wave. In the blue work, the same form has been turned upside down: the whorl unwinds as it ascends the wall. The works extend several floors. The works belongs to the collection of the City of Helsinki, managed by HAM Helsinki Art Museum. At map
