When you open a web browser, you have a collection of images or videos that you can view. To view all of these, you need to have a compatible browser that has the Gridlock extension installed. With this extension, you can view all of these in a new way.

The beauty of this extension is that it will apply the symmetry grid to all of the images on the page. The way that it works is pretty simple: when you open a page, it will detect all the images and videos and apply the grid to them. If you want to view a specific image or video, you can simply drag it into the browser, and it will automatically apply the grid to that image or video.

This is really useful when you want to study images.
