If you find visual illusions fascinating Programming Visual Illusions for Everyone is a book
for you. It has some background some history and some theories about visual illusions and it
describes in some detail twelve illusions. Some are about surfaces some are about apparent
size of objects some are about colour and some involve movement. This is only one aspect of
the book. The other is to show you how you can create these effects on any computer. The book
includes a brief introduction to a powerful programming language called Python. No previous
experience with programming is necessary. There is also an introduction to a package called
PsychoPy that makes it easy to draw on a computer screen. It is perfectly ok if you have never
heard the names Python or PsychoPy before. Python is a modern and easy-to-read language and
PsychoPy takes care of all the graphical aspects of drawing on a screen and also interacting
with a computer. By the way both Python and PsychoPy are absolutely free. Is this a book about
illusions or about programming? It is both!
