Bret Victor-style dashboard and visualisation systems. I 've been using Qlikview, Tableau and Excel for years and they are all very limited in what they can do. New dashboard solutions come out every hour but everyone is copying each other. I want something that I can mould to my problem, that I can touch and fully interact with. Hard, hard problem but worth spending time on this. Make it work in real-time scenarios too please.
Wish this jumped higher in the thread. I mounted a cheap digital projector and a web cam pointed down over a white melamine table in my workshop thanks to Bret's "Seeing Spaces" talk.
Just being able to record and play back what happened on the table has changed the way I work on things. A commercial version of this project would be huge.
Wish more people were thinking like Bret Victor. I 've been working with visualisation systems for more than 16 years and never seen anything like his software. The tool that he uses to easily construct charting within a few minutes is genius
