Stable (green) and Canary (yellow) app icons now use Ace's four-lobed mark instead of the old A from ace-old.

  • Mark: apps/desktop/icons/mark.svg is the AceAvatar hypotrochoid, tilted 7° counter-clockwise to match the site. It's rendered at 8× and traced (potrace) into one filled path. ace-avatar.svg's 360-segment polyline facets at icon sizes, which was the artifacting.
  • Sources: ace.icon and canary.icon are Icon Composer documents: a white glass mark on an automatic gradient, styled after the earlier Ace Icon.icon.
  • Iconsets: every PNG is rendered from the .icon with Icon Composer's ictool and placed on Apple's 1024 grid (824 tile, soft shadow), like actool's legacy .icns. iconutil -c icns accepts both sets.
  • icons/readme.md records the parameters and commands.

Not done: shipping the .icon itself (Assets.car + CFBundleIconName) for macOS 26's glass and tinted variants. Electrobun builds from an iconset today.

Built in Ace

No. Claude Code worked outside Ace, using Icon Composer through Desktop Tools and its ictool. Ace has no image tooling. Tracked under #5.

Stable (green) and Canary (yellow) now show the four-lobed AceAvatar mark on a macOS-grid tile. Each PNG is rendered from an SVG source at its own size, and the mark is sampled finely enough not to facet.
The mark is tilted 7° as on the site, traced to a filled path, and composed in Icon Composer (ace.icon, canary.icon). The iconsets are rendered from those documents with ictool on Apple's 1024 grid.
