Tilted Table Illusion

Requires a Wolfram Notebook System

At first glance, it may seem like the weight is tilting this table. However, if you remove the weight you will see no change in the table—yes, it's a trick. Try tilting the table and making it flat by adjusting the tilt. Once it looks flat, upon removing the hatching you will notice that the table is not flat at all. This is a variation of the Zöllner illusion, where diagonal lines distort our perception of parallelism. Enjoy!
