Ivan Sutherland's Ten Unsolved Problems

1. Hardware characteristics and cost
2. Problems of technique (e.g. rubber banding)
3. Coupling problems (display-to-simulation)
4. Describing motion
5. Digital halftoning
6. Structure of drawings (making the structure explicit)
7. Hidden line removal
8. Program instrumentation (and visualization)
9. Logical arrangement (e.g. hierarchical modeling)
10. Working with abstractions (e.g. scientific visualization)
