Data bending is like playing with a toy. Remember when you played with a toy and changed its shape or added different colors to make it look cool and unique? In the same way, data bending is where someone takes a picture or sound file and changes its shape or adds different effects to make it look or sound interesting and different from its original form.
Now, imagine you have a picture, and you want to make it look like it's melting, or you want it to have strange colors. Data bending lets you do that! You can use special computer programs or even just a text editor to mess with the picture's code or data.
When you change the code or data, you're changing the way the computer sees the picture or sound. Sometimes it creates cool new patterns, and sometimes it makes weird and funny-looking pictures or sounds. People use data bending to create art, music or just to have fun!
