I don't use matlab-esque tools that much, so I can't really comment on the functionality, but from a web dev perspective, it's really cool! How long did it take you guys to build it?
It took two of us about 6 months, with one of us part-time and a few friends helping after their day jobs.
Dude, that click-drag is nasstyy! Great work.
It feels confusing and distracting, not affording a "zoom" function.
Looks awesome - and a bit overwhelming at first. Perhaps include a link to the tutorial in the very first popup window?
Great work! UI is amazing and very impressive, except that "zoom" context menu.
