No acid involved...

Oh, who doesn't love a bit of a play with spinning lights in the dark after several beverages??

Me and my deliciously mad friend Lord Flashheart* got together for a session of 'who can eat their body weight in cheese", and look what happened.

Kinda trippy. No acid involved.

*Not the Lord Flashheart variously described as vain, arrogant and narcissistic, from Blackadder. The other one.
