Since no one mentioned it yet, i'd like to mention that Rootstock (RSK) exist. It's Bitcoin sidechain which support smart contract with merged mining to Bitcoin network.
Technically you don't make Bitcoin turing complete. Did you actually put some source code on Bitcoin blockchain by splitting it every 20 bytes on each address and create website to parse the transaction and compile/run the source code?
bitfossill is a simple free text search \ web front end for apertus.io
an apertus.io monitor is running on the bitfossill webserver... this monitors the bitcoin MEMPOOL and many other altcoin MEMPOOLS in realtime for data archived in the apertus.io format. bong-ball is a fully embedded game that can be played with nothing but apertus.io and a fully synched bitcoin blockchain a traditional webserver is not required.
the entire game is embeded within bitcoin transactions as you have mentioned..it is a complete HTML5 website that references jquery which was also archived on bitcoin earlier using the same software....it is a demonstration of code reuse and application deployment...apertus.io creates a master root index of all archived data that can be referenced in future applications like so <script src="../f5e8166c30fd080f9c5f0ab79a57b058e0d31364f8064f39badddff2675f754b/jquery.min.js"></script>
bitfossill's purpose is to let you search and access the data using traditional web browsers.
