In the main room of Knowhere, look for the curtain of vines stage right.
Slice them away, and use the console for a very simply memory game.
After that is a maze interface- you have to move the cursor over the arrow keys in the top left corner of the graphic to get it to respond.
Don't worry about your moves- anything you do will cause the screen to blow up. Build the pieces into a sliding tile puzzle. As ever, watch it scramble itself to see the best way to unscramble it.
This completes the task, and a gold brick is replicated for you downstage center.
