A slow-motion-ifyer allows you to slow down everything around you, but not you yourself. So for example, if you are taking an exam and you need more time, you can just slow the whole room down, and voilà, take as long as you want.
The Slow-Motion-Ifyer was developed by Mgadigadi Technologies, and invented by their CIO (Chief Inventions Offer), Dr Jezebel Terracotta-Glandsmitten himself.
The development process of the device is quite an interesting story.
Dr Terracotta-Glandsmitten and colleagues were making slow, but very solid progress on it in the winter of 2001. Now Dr Terracotta-Glandsmitten, while we must add, is brilliant, he is very sloppy with his math. While working on the sub-algorithm for the quadruple-beni-haha-valve valve (which as you know, being a valve valve, is critically important for the device), he got the sign wrong on the main input number. It should have been a minus but instead he input a plus. The result was when they tested the first device, instead of slowing everything down, the opposite happened and it sped everything up. Because of this, they all started working really fast. Dr Terracotta-Glandsmitten realised the error, but chose not fix it because it meant that they would all continue working with speed. As a result they actually developed the technology one year quicker than they otherwise would have. Once a new and correctly-functioning device was built, he slowed everyone down.
Very clever Dr Terracotta-Glandsmitten. Very clever indeed. We can see why you’ve won the Ihmfin-hizz-hizz Prize multiple times.
