- **Browser‑first approach** – "I think there's something to that." – Lerc  
- **Universal key mapping** – "That combined with ... gives an etch a sketch program and enough information of how to convert it to WASD which seems to be a universal impulse amongst 9year olds." – Lerc  
- **Processing skepticism** – "Why not using Processing?" – q2dg
