Have you played Descending ? https://ldjam.com/events/ludum-dare/48/descending

After a huge load of valuable feedback screaming about how the game is mostly dark breaking completely user experience, we've been working on new lighting props of many hights to spread a lot of lights across the level, however, through some procedural wobbling, make these lights randomly oscilates between colors, ranges, intensities and randomize it's own sprite being used for light's flare / cookie! Monique Moon (https://www.instagram.com/moniq.moon/) designed all the props art for modularity and multiple layers of stacking!

As the final result of our effort, the "wobbling lights" creates many patterns of light and shadows constantly, and the props generates an awesome composition almost without perceivable repetitive patterns!
