I recorded a 47-minute tutorial on how I use Opus 5.5 to create designs with gorgeous three.js scenes. I've been using Mobbin MCP to give my agents strong references, then letting Opus bring them together into a full landing page with multiple sections and a consistent design. Opus also created a super detailed brand guide, logo explorations, and some amazing ad creatives. Went way beyond my expectations.
