Mechanically minded Russian sculptor Eduard Bersudsky has set about establishing a cast of clanking and spinning contraptions at Glasgow's Sharmanka Kinetic Theatre: a darkened room, stuffed to bursting with performing machines that meld Russian and Scottish folklore with an understated social and political commentary, all to the accompaniment of an eclectic musical soundtrack. It is as unusual as it is unnerving, a mysterious toymaker's midnight workshop. This is the unpredictable stuff of dreams, and not necessarily nice ones, the sort that keep you clutching the sheets, wide eyed, nervous of what sleep might bring.
