On his participation-sheet for Vision in Motion, Uecker calls his works ‘Objecte’. The monochrome white and yellow canvases on panel, and a wooden ball as well, are all provided with rows of nails that produce waves through the play of light and shadow. Their changeable character invites the viewer to alter his/her standpoint too. The contrast between the rough finishing and the optical effects lends his early work an unmistakable charm.
