Product Description

I have found a class of objects for which the appearance of each member changes drastically when it is reflected in a mirror. A typical example is a roof of a garage: it appears to be a rounded roof, but when reflected in a mirror, it changes into a corrugated roof. We named this class of objects “ambiguous solids”.
A rigid object and its mirror image should be mirror images of each other; the object cannot change into another shape. Therefore, what is happening to the reflection is not a physical change, but an optical illusion, created by the perceptual system in our brain.
This book shares the joy of ambiguous solid illusion.

Product Description

There are many times we encounter with the question of what to do with, for example, with a glass bottle, which by its form or its particularity, we do not want to throw the glass to the container. At the same time, we do not know this for what can serve us.
This happens to us because although we like the bottle, their potential is not exploited.
This manual is for to provide for these objects in glass, an original charm that no leaves us no doubt.
With the procedures and results presented, we shall be able to recycle any glass container and turn it into a unique, original object, which monopolizes all the attention in any of the areas of the house where it is exposed with a highly decorative capacity. With this book we want to provide to the objects of a new functionality and, better still, with a ridiculous investment.
