Dev builds 135 editable CSS 3D experiments with Claude Code in about a day

Developer Edgaras Neverdauskas built CSS 3D Lab in about a day with Claude Code: a free, open-source (MIT) gallery of 135 live CSS 3D effects, each with editable code, a short explanation, and a downloadable video, across 103 commits.
Workflow takeaways:
- The key wasn't one perfect prompt but turning every visual bug into a written rule that the next helper agent had to read — e.g. a rolling button flickering as the element rolled out from under the pointer, rounded dice showing daylight at corners, 40% of sampled points on a ripple demo hitting an invisible container.
- Claude couldn't see one GPU-specific edge problem in its test browser; the author compared variants on his own screen and established a practical distinction: broken/dashed edges are bugs, slight stair-stepping on slanted surfaces is a browser-rendering limit.
- His first prompt asked for a searchable gallery of SCSS 3D effects; six minutes later he added the crucial instruction to make it an educational app with copyable code per example.
- Claude wrote almost every line; he handled product direction, blocking bad changes, visual review, and testing.
