Real image compression (JPEG, PNG) uses different techniques (DCT, entropy coding), but quadtrees capture the same principle: spend your bits where the detail is, not uniformly across the whole image.
The Dreamie is refreshingly compact, too. It takes up significantly less real estate on my nightstand than the Philips Wake-Up Light I've been using forever, or something like a Hatch Restore. The smaller footprint is something I appreciate as a person always battling cluttered surfaces. That also makes it better for travel. Since podcasts and sleep insights aren't available yet, I haven't been able to test those out, but they're non-critical features for me. The company has shared an estimated timeline of Q1-Q2 for these features to arrive, with podcasts likely coming first. They'll be nice to have, podcasts especially, but the Dreamie is more than able to do its main job of creating an environment that supports better sleep without those things.
