I've been obsessed with LEGO mosaics for years, but the workflow was always painful — pick a photo, manually match colors to real parts, figure out quantities, order the right pieces, then build without losing your mind on a 9,216-piece grid. Existing tools gave you a pixelated preview and called it a day. No parts list, no build instructions, no cost estimate. You were on your own. So I built BMBrick. Drop in any photo, get everything you need to actually build it: color-optimized preview, PDF instructions with symbol-mapped 16×16 pages, parts exports for LEGO Pick a Brick / Webrick / BrickLink, and real-time cost estimates. The thing I'm most proud of is the color engine. We use OKLab perceptual color space instead of RGB — it matches what your human eyes actually see, not what a computer thinks looks similar. Tested against other mosaic tools and the difference is visible. Also added Magic Cut (AI background removal) which can reduce part count by 60%+ — that's hundreds of dollars saved on a large build. Would love feedback from anyone who's tried building a LEGO mosaic before. What was the most frustrating part of the process for you?
