I've tried replaying this a couple of times and I still have no idea how I'm supposed to win. I tried looking at the orange, looking at the people. Walking around. I just have no idea what to do.
Have you found that some things move if you long look at them? (let the cursor do the full animation.) There is an order that you have to get before Oppenheimer reaches the table. If you get a big orange on the table, then you solved it and just need to wait for Oppenheimer to reach it.
