Curl and Pogo.com, a popular on-line game site, discussed a partnership. Curl would develop games in the Curl language that Pogo.com would host. Pogo.com presented Curl with several game concepts. I elaborated the ideas for a game called 3-D space hockey. I described how a Curl game would be set into the Pogo.com site, filled in gaps in the concept document to create a playable game, and used Ray Dream Designer to create 3-D renditions of the game. The result was a design document that provided the development team enough detail to permit implementation. The image below comes from that design and depicts the game embedded in the Pogo.com web site.
