I agree, with the luxury of hindsight, that it was a rather garish era in UI. But looking back now at his Kai Power Tools (the first I heard of him) it is clear to me he was more responsible than anyone for kicking off that whole era of wacky UI that culminated/ended with brushed metal and Apple's Aqua.
So kudos to Kai for having such an outsized influence on the UI of the time.
