Croes was born in La Louvière, Belgium, and lives in Brussels. In his biography on the website they state that he always begins a series with a set of rules, akin to the rules of his favorite game, Yahtzee. Personally I remember playing that with my grandparents. I should give it another whirl.
The site also describes these pieces having something totemic about them which is obvious even at a glance. You can see and read more HERE or at the gallery link above.
