how to send and save
saving your creations
press the "file" button on the menu bar to open the file menu. from there you can save models to a file, or load ones from earlier
sending models to your friends
if you click the "share" button in the file menu, a bunch of letters will be added to the url in your address bar
if you send the new url to somebody else it will load your model automatically!
file format
the text at the end of the url is your model, translated into base64 encoding. using any public decoder will turn this into a json object describing your model
this json object contains all of the details about the masses and springs within your model, as well as configuration values such as gravity and friction
an experienced user could use this format to make precise edits to a model that would not be possible in the normal constructor!
