Is there a Scratch website available for the Solidity language? The only one I could find was Etherscripter.com however that one is only for Serpent.
There is browser solidity, which allows you to compile but does not seem to include the full functionality of EtherScripter: http://chriseth.github.io/browser-solidity/
ArabianChain is developing one using blockly as well and it'll cover Solidity, Serpent and Thuraya. It'll be ready in June 2017.
this is a pre-launch video , not that attractive yet but it'll show the builder. https://www.youtube.com/watch?v=MbaZ6f4AFhs
