Mystery #2 - The Holy Ruler
What makes your 30cm ruler special? Not much I would think. However I'd bet that you have never seen anything like this before.
Look at the picture below, nothing much is it? Just another ordinary ruler capable of ruling a 30cm straight line in less time than it takes Superman to run around the globe.

However hold it up to the light and what do you see? Images that do not appear on the back or the front. They are inside the very heart of this ruler! Why are they there? How are they there? And most importantly, who put them there???
Could this be the Holy Grail of Office Stationery? Is this a sign from above and beyond?
