Archive for the 'Optical illusion' category

Some people have been telling me: “You blog! That must take a lot of time and you must be there each and every day”.

Don’t worry, I may post something on Roumazeilles.net every day, but it does not mean that I am in front of the keyboard every day. Far from it. I am using one small advantage of WordPress (the software package supporting my web site). I can write posts and schedule them for future publication.

That way, I have no limit to my inspiration. For example, I have currently scheduled weekly posts about optical illusions for the coming 6 months, a full week of feline-related news (daily posts next week), a full week of daily videos titled “when XXXXX get bored” in a couple of months.

Everything is moving if you stare at this optical illusion.

You just have to turn your head 90° to fully change your perspective.

This is a special gift to all readers from Ireland: You are continuously the country where visitors spend more time on this web site (more than 4 minute per visit) from all countries contributing more than 20 visits per month.

Special for St Patrick’s Day: If you stare at the image, the clover leaves will start moving.

When straight lines are no longer straight.

Of course, you know about the impossible triangle (very classical optical illusion).

Do you know how to draw it? It is complicated indeed and most people will do some ugly sketch instead of a nice optical illusion. However, this is quite simple. It is all a matter of starting it right thanks to the help of: “How to Draw an Impossible Triangle“.

You know it, the two vertical bars have the same length. But your brain will not let you see it. Don’t fight! Your brain is your master.

It is easy to find the two main characters. But did you notice that there is a total of nine human representations in this painting?

How much time will it take for you to find them all?

Try and find some really straight lines!

Duck or rabbit?

Boats, clouds, arches?
