Didn't need the sphere or laser, and the timer never turned off. Didn't like this chamber for the reasons Mr Fraggle stated.

I think u couldn't understand this map because look to map's name:"Unusual" Parts.In this map,there're some unusual parts like that sphere and laser.You can pass this test without using them.I placed them for differency.

Not a nice map at all,no real sense of where to go or what to do. I was left with a ball and could not see anywhere to place it,perhaps also I was supposed to do something with the laser,I have no idea. Its your first map so well done for taking the trouble.
