I actually think it is meant as a joke. The paper and code he made available seems be something he actually made, and that without looking into the gory details seems to be doing what the video says it does. That said, the conference it supposedly was presented at is clearly a hoax, and did supposedly happen on April 1st.
If the demo and code is real, it's incredibly impressive whether or not he's laughing while he does it
SIGBOVIC isn't actually a hoax: it's a real conference. It's just that it's focused on the absurd and the silly rather than real science.
