Resonance of 4 (1994) is a collaborative music-creation artwork consisting of four adjacent stations, each comprised of a small podium bearing a computer mouse, a 16-by-16 grid projected onto the floor from a video projector above, and a cursor connected to the mouse. Dots can be placed in each of the grid's cells by clicking with the mouse. A synchronized bar sweeps across all the grids simultaneously, triggering musical notes wherever a dot has been placed. Sound is relayed over a loudspeaker system, and the notes from all four stations are superimposed, although each station has its own musical tone. This work was shown at the Serious Games exhibition at the Laing Art Gallery, Newcastle in 1996 and 1997 and at the Barbican Arts Centre, London in 1997.

A music and image based artwork where enjoyment of the work depends heavily on the ability of the four participants to co-operate in play with each other. Iwai provides an elegantly conceived 'shell' which the audience can use as a communal creative tool.
