While most of the lasers at the B.A.D. satellite station are easily avoided when they turn off, the second set inside the control center is particularly difficult. The first jump is easy, but you have to land between the two lasers on the second jump. The best way seems to be waiting a second after the first one turns off, then jumping as "flat" (sideways) as possible, so that you arrive on the platform after the second beam also turns off.
(There may have been some kind of clever trick designed here, but there does not seem to be an easy answer.)
Once you duck past the Security Room, and hide behind the statues to avoid the lasers, exit through the doorway at the right and go to the painting The Scream in the gallery.
You can't turn them off. You have to slip past the Security room and the lasers in the Statue Room when you enter the museum at night. Hide behind the statues until the lasers move away, then work your way slowly to the door at the left side.
Get past the lasers to the transporter control. Type in the three passcodes, one at a time: laser (enter), hair (enter), removal (enter). Director D turns out to be one of the Bald And Dangerous (B.A.D.) guys.
You have the picture that shows how to move the features on the Dragon Face, and you have the key to the Supply Room. Duck past the Security Room, and hide behind the statues to avoid the lasers in the Statue Room.
you stand behind all the statues
Duck behind the statues, then move right when the lasers move away. When you get close to the door, go out into the gallery.
Although you slip past the Security Room and dodge the lasers in the statue room, you are supposed to be caught at the painting (The Scream). Later, when someone else actually steals it, you have to help catch them.
You hide behind the statues until the lasers pass. Then you can enter the art room and go up and click on the Scream.
Avoid the moving lasers by hiding behind the statues, and make your way to the right when they move away. Eventually you can make a run to the gallery door.
When entering the museum at night, you slip past the security office and then avoid the lasers in the statue room. When you reach the painting, jump onto it. This may not seem wise, since you immediately get caught...but it is the next step in the quest.
Break into the museum through the supply room hatch (the dragon face). Slip past the security room and past the lasers in the statue hall. Now you can climb up on the light and jump down to surprise the thief. (Not the best plan, and it wasn't your idea.)
Duck past the Security Room when you don't see the shadow on the window blinds. Then hide behind the statues to avoid the lasers as you make your way to the exit at the right side.
