Cheerful greetings and salutations to all of my fellow earthlings, i mean humans, i mean fellow non aliens....err...just hello ok? So here is a large portal of sorts. Just like any portal, it is not ALWAYS a good idea to just stroll through it. Side effects might include nausea, runny nose, explosive spontaneous implosion, leaky eyeballs, and extreme quantum molecular cellular hiccups. Also has been known to cause laser sneezing. On the positive note, you might find something cool in there...
Think I might give this portal a miss, last time I had a bout of laser sneezing I had to replace the kitchen.
Sorry to hear that ;)
