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.

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).
