Mattermost Christmas Magic
Mattermost Christmas Magic is a high-performance, commercial holiday plugin for the Mattermost enterprise collaboration platform. Designed to bring festive spirit and team engagement into corporate workspaces without compromising productivity or system speed, it adds lightweight physics-based snowfall, an original animated Santa sleigh with synchronized sound, interactive gift box drops with customizable joke reward cards, a walking snowman over the message input bar, and a rotating 3D Christmas tree featuring a live community wish boardβall controllable via individual user toggles and an enterprise admin console.
π Key Features:
Lightweight Physics Snowfall Engine: Multi-colored, spinning snowflake particle simulation using HTML5 Canvas with device-aware density scaling, throttled particle counts, and auto-pause when browser tabs are hidden to maintain 0% idle CPU footprint.
Animated Santa Sleigh Flight & Audio: Custom-drawn SVG Santa sleigh and reindeer with random altitude and flight intervals, paired with a bundled, synchronized festive audio clip (sleigh bells, jingle melody, and Santa greeting) with an independent user-level mute control.
Interactive Falling Gifts & Reward Cards: Presents dropped along Santa's flight path that land and bounce onto the message box, opening on click into festive joke or custom corporate reward cards ("You've been promoted!β¦ just kidding π") personalized by user first name.
Walking Snowman & Input Docking: A responsive animated snowman that tracks and strolls along the top edge of the message composer without intercepting clicks, text selection, or keyboard input.
3D Rotating Christmas Tree & Wish Engine: A low-overhead 3D tree anchored to the message composer that broadcasts live team wishes in speech bubbles submitted via the /christmas <wish> slash command, cycling recent wishes in real-time.
Enterprise Admin Governance & Moderation: Full administrative controls in the System Console to set scheduled start/end rollout dates, tune flight frequencies, configure gift messages, and review or delete inappropriate submitted wishes in real-time.
Hardware-Bound Licensing & Offline Resilience: Server-side licensing tied to Mattermost diagnostic installation IDs, featuring automatic background activation, tamper protection, and a 7-day cryptographic offline grace fallback against remote auth outages.
WCAG & User Autonomy Compliance: Full user privacy and accessibility support, respecting OS-level prefers-reduced-motion flags and offering individual persistent header toggle switches without polling the server.
