we have done multiple projects where we punted on big questions and built an app anyway—we don’t feel can learn much from yet another project in that vein (e.g., inkbase again but with different programming model) we have done multiple projects where we focussed narrowly on a computational model but not the overall app design—we don’t feel we can learn more right now from yet another full-project computation model experiment (e.g. crosscut or untangle again but with yet another new programming model) If we can answer these key questions and figure out a cohesive design—both for the app in general, but especially for the inking and programming affordances and gesture space, then we could be ready to implement a usable app as a larger project.
