As said in my thread in the Bacon Uplink, it is possible to get into the barrier in Loboto's lab. All that needs to be done is levitating into the pillar part of the barrier and floating down, making sure not to hit the actual dome part. Fun with Loboto ensued, such as blocking his path, riding the brain, etc. I had to take pics.
(Btw, thanks for making this thread! It's an awesome idea.)
