Hi all, I've become interested in visual programming languages, but a bit disappointed that visual notation tends to be based on topological rather than geometrical relationships. In fact the only example of a computer language using geometrical notation I've found is the ReacTable and the related TurTan, which use relative orientation and proximity of symbols. Are there others?
Also, perhaps a more interesting question is, why aren't there more? I can see why you wouldn't want (practically) continuous parameters of distance involved in business logic, but how about programming languages for use in the arts? alex -- The Open University is incorporated by Royal Charter (RC 000391), an exempt charity in England & Wales and a charity registered in Scotland (SC 038302).
