We designed three towers which change configuration using electricity and oil pressure, exhibited in the International Exposition Tsukuba, Japan, 1985. 'Revolvo-balance Tower' is composed of 3 bars coupled by pins successively. Because of the eccentricity of mass, this tower moves very irregularly. 'Dancing Tower' is composed of 2 rigid trusses coupled and supported by 2 groups of 6 bars. Because of the geometrical characteristic, 2 trusses translate in holizontal circle. 'Extenso Tower' is composed of 2 groups of 8 triangular prisms coupled by pins. Because of the geometrical characteristic, the 2 groups moves simultaneously changing configuration, from folded to extended and from extended to folded.
