Oh, yeah, the D-League Showcase is an event where they bring all the teams to one location and play multiple games to show off for scouts.
Here's a list of the players named to the 2011 All-D-League Showcase teams. Lin and Aldrich where the only NBA-assigned players among them, but I would guess all of them have a reasonable shot of being more useful as your typical NBA minimum salary journeyman.

Jeff Adrien, Rio Grande Valley Vipers
Joe Alexander, Texas Legends
Othyus Jeffers, Iowa Energy
Marcus Landry, Reno Bighorns
Jeremy Lin, Reno Bighorns
