Custom swamp-themed avatar generator with daily rerolls

Summary

Let operatives customize parameters for a procedurally generated swamp-themed avatar on their profile. Avatars are auto-generated from the chosen parameters, and users can reroll up to 3 times per day to get a variation they like.

Motivation

Generic default avatars don't fit the swamp aesthetic. A custom avatar generator gives every operative a unique visual identity that's on-theme, without requiring them to upload an image. The reroll mechanic adds a fun daily interaction — "what will my swamp creature look like today?" — while preventing infinite generation abuse.

Design sketch

Avatar parameters

User-selectable traits that feed the generator, e.g.:

• Creature type: frog, gator, newt, turtle, heron, catfish, etc.
• Color palette: murky green, bog brown, bioluminescent, toxic purple, etc.
• Accessories: moss crown, lily pad hat, swamp gas aura, cattail staff, etc.
• Expression: stoic, menacing, goofy, wise, etc.
• Background element: cypress tree, fog, fireflies, bubbling mud, etc.

Parameters are stored on the profile. The combination + a seed value produces the avatar.

Generation

• Server-side generation from parameters + seed (deterministic — same inputs = same output)
• Output as SVG or PNG, cached/stored after generation
• Reroll changes the seed while keeping the chosen parameters

Reroll mechanic

• 3 rerolls per calendar day per user
• Reroll counter resets at midnight UTC
• Each reroll generates a new seed, producing a different variation of the same parameter set
• Changing parameters does NOT consume a reroll (only the seed changes on reroll)

Storage

• Avatar parameters + current seed on the profile document (or dedicated collection)
• rerollsUsed + rerollDate for daily tracking
• Generated avatar cached in S3 or as a static asset

Profile UI

• Avatar displayed prominently on /u/{username} and in leaderboard entries
• Parameter editor in profile settings with live preview
• Reroll button with remaining count indicator

Open questions

• Generation approach — deterministic algorithmic (SVG compositing), AI-generated, or pixel art?
• Should tier influence available options (e.g., higher tiers unlock rarer traits)?
• Avatar size/format constraints for leaderboard thumbnails vs. profile display?
• Should rerolls be a scoring event or purely cosmetic?
• CDN/caching strategy for generated avatars
