Hi Fiddian here director of Soda, creators of Sodaplay. Thanks for your kind words about Sodaplay. We developed iOS and HTML5 prototypes of Sodaconstructor a while ago which work nicely. It is however a significant amount of work creating a new backend to support the million or so models we have in the database and porting the other tools like Moovl. We are planning to do a Kickstarter to raise funds for the dev work, but need to clean our database of 250,000 registered users' emails which costs money otherwise we'll be instantly blocked as spammers. I very much hope to have the Kickstarter online, bring Sodaplay up to date and reinstate a lot of the version 1 features people liked e.g the zoo!
