World
building

Over 5 days, you'll build your own world from the ground up, drawing directly from Joseph's process on Marathon, Destiny, Dune, Dead Space, and Foundation. Joseph and Simon specialise in character-driven worldbuilding: the factions, silhouettes, uniforms, and equipment that make a universe feel real and inhabited. You'll leave with a personal world project anchored by its core characters and visual language, developed with daily feedback from artists who shaped Marathon at Bungie.

Day 1
Joseph opens the week with his process on Marathon. How "graphic realism" became the backbone of the world, and how factions and characters anchored it. Simon launches your assessment exercise and sets your creative brief: the world you'll build this week.
Day 2
You start building your world. Simon works alongside you, guiding your visual research, validation, and early design decisions around faction structure and core silhouettes.
Day 3
Character and faction development. Silhouettes, equipment, uniforms, gear. The elements that make your world feel inhabited. Daily feedback from Simon on your visual language and consistency.
Day 4
Refine your world into a cohesive package. Your characters, their environments, and the visual language all speaking the same dialect. Simon helps you prepare your final presentation.
Day 5
Joseph returns. He reviews every project, critiquing your world, your characters, and your visual choices, then shows you exactly how to elevate them. The same feedback loop he uses on his teams.

Prop
Design

Design a complete prop ecosystem for your world. Sheng Lam takes you inside his ideation process. How he turns references into iconic, coherent designs for AAA games and films. You'll leave with a collection of props that tell a story together.

Known online as @8bitwizard. His HanZi series of props built around Chinese typography is a reference in hard-surface design.
ArtStation
Day 1
Inspiration and the creative muscle. Sheng introduces his method: the observing eye vs. the perceiving eye. How everyday objects, food science, and cultural traditions become raw material for design ideas. You pick your world and start gathering references.
Day 2
Extracting design ingredients. Learn to break any reference down into its key components: proportions, shapes, hierarchy. Build your first "recipe list" and start cooking: rearranging ingredients into new prop concepts for your world.
Day 3
Theme combination and art direction. Combine unexpected themes to create something original. The way Blasphemous mixed Spanish folk tradition with dark gothic, or how Sheng turned social media brands into retro audio hardware. Apply this to your prop ecosystem.
Day 4
Time to cook. Scale up your designs, push variations, and learn when to pull back. Sheng covers over-detailing pitfalls, readability hierarchy, and how to maintain consistency across a full collection of props. Refine your strongest pieces.
Day 5
Final presentations. Sheng reviews every project, critiquing your prop ecosystem, your recipe list, and your creative decisions. You leave with a coherent collection and a repeatable ideation process you can apply to any future project.
