Optical illusions are a fun and interesting way to challenge our brains and sharpen our observation skills. Sometimes, what we see at first glance is not the complete picture. There are hidden within ...

This video shows the process of drawing a geometric optical illusion using repeating black shapes arranged in a circular pattern. The design creates a striking 3D vortex effect that appears like a ...

Spatial carrier fringes in different directions, each recording the 3D information of the object at different time points, are captured and superposed through time integration within a single camera ...

For decades researchers have been exploring how to store data in glass because of its potential to hold information for a long time — eons — without applying power. A special type of glass that ...

3D shapes aren’t just geometry—they’re a gateway to building spatial reasoning, problem-solving, and early STEM confidence.
