1998 to 2001 he was Artist in Residence at Mixed Reality Systems Laboratory in Yokohama, Japan. Video games Iwai is the first internationally recognized gallery artist also to have led the creation of several successful commercial video game projects. This cross-disciplinary ability typifies Iwai's career. Iwai's first game was the musical shoot 'em up Otocky (1987), produced in association with ASCII Corporation for the Famicom Disk System, an add-on for the NES available only in Japan. The game is notable for being the first to include creative/procedural generative music. Through association with different game mechanics and player actions, the game plays quantized-in-time musical notes in a variety of digitally synthesized voices. Otocky is a precursor of Rez, Tetsuya Mizuguchi's 2002 Dreamcast and PlayStation 2 game exploring similar themes of player action and musical evolution. Later, leveraging work done on the 1993 installation art project Music Insects at San Francisco's Exploratorium, Iwai created another sound-based game in 1994 for the Super Famicom system called Sound Fantasy. In the game animated insects traverse a grid containing colored dots. As the insects pass over the dots, musical scales, sounds, and graphical effects are triggered. The player can select colors from a palette and paint on the grid, triggering new results and changing the insects' direction, improvising a visual music performance. However, the game's release was cancelled and it was eventually converted into the PC title SimTunes, published by Maxis, a division of Electronic Arts. In 2000, Iwai worked to publish , a collaborative drawing game that became the PlayStation 2's first mouse-compatible title. This was followed in 2001 by the limited-edition release of a simple step sequencer, , for the WonderSwan. This non-game would be the precursor to the more advanced 2005 version released together with Yamaha. Iwai's acclaimed Electroplankton for the Nintendo DS was released in Japan in 2005 and in Europe and North America in 2006. A suite of ten different interactive music and audio toys themed around cartoon plankton and using the novel touchscreen and microphone interface features of the Nintendo DS, Electroplankton draws heavily on Iwai's earlier work, including Composition on the Table.
