While digging a new tunnel in the EXSP laboratory, some minotaur workers stumbled upon an ancient vault. Buried deep beneath the ground yet strangely preserved, they found inside the dusty chamber an old grimoire labeled "Aperture Magic
(TM)", filled with strange runes. On two alcoves also rest two strange stone rods with gems at their ends, one orange, one blue. The book and artifacts was carefully brought back to the chief archeologist of the Laboratory who, after weeks of study, managed to slightly grasp the power contained within. With the help of other mages, he managed to reactivate the magical rods and harness their unique spells... but how this magic worked was beyond their understanding and will probably forever remain a mystery. The artifacts were thus kept in the Laboratory test rooms with utmost care as the enchantments bestowed upon them were impossible to reproduce, without mentionning the dangers of releasing this power to the world above where it could easily fall in the wrong hands.
Ok folks, the spell man has another gift for you:
Portal for Grimrock!

Or just download the Lab .dat, head down the stairs to Test Room 06 and play with it yourselves:

I'll update exsp to 1.4.1 in the next day or two due to some little bugs reported back 2-3 people, and will release the Portal source scripts/textures with it.

I could always just teleport the monster with a random chance if he happens to face the wall, maybe with a puff of smoke, but I'm not sure how convincing it would look.
