Software package providing an interactive graphical interface for computations in dynamical systems and visualization of resulting geometric structures, designed for researchers and educators studying dynamical systems (both differential equations and discrete time systems). DsTool readily produces nice pictures for both discrete and continuous systems.
SciCrunch is a data sharing and display platform. Anyone can create a custom portal where they can select searchable subsets of hundreds of data sources, brand their web pages and create their community. SciCrunch will push data updates automatically to all portals on a weekly basis. User communities can also add their own data to scicrunch, however this is not currently a free service.
