this was Brian's IPP Exchange puzzle from 2009 (San Francisco), made from Papua New Guinean rosewood (frame) and Australian jarrah (tiles). comes with original solution sheet and description card.
from the original description on the Mr. Puzzle site:
The object of the puzzle is to take a drive down Lombard Street, from Hyde Street to Leavensworth Street. Manoeuvre the ball bearing from tile to tile, starting at Hyde Street and deliver it to Leavensworth Street. Beware, a wrong move can cause a crash, forcing you to start all over again at the top.
To do this you will need to complete this dexterity slide puzzle. This sliding block puzzle is very different to others. Firstly, you cannot touch the tiles that you must slide because they are behind perspex. You must use dexterity to do this. Generally, more than one block at a time will be moving which means you must think many moves ahead. Secondly, you use the blocks that you are sliding to deliver the ball bearing from top to bottom of the puzzle.
This is like a maze because at the same time you are sliding the blocks you are forming the maze-like track that the ball bearing must take to arrive at the bottom. Most of the pieces are different; that is the tracks in each tile that carry the ball bearing are different. There are many different ways of solving the puzzle, some with more or less dexterity, but Brian intended that the ultimate solution would be to manipulate the ball bearing with very little dexterity; ie: a minimum number of block movements.
