The layout is inspired by Mael Ruffini, a simple grid with a bunch of images. You can add more to this, like change the image to videos, make it autoplay, and set the grid and grid-gap according to what you like. It's a base canvas for you using GSAP Flip to create a seamless transition from Small, Mid, to Large group of images. Enjoy! Follow for more stuff I find inspired on the net.
