Yesterday I found some early R&D work I did for Justin before joining the team in Spain (april 2009).
These videos are from the early days and we ended up redesigning almost everything, but it's interesting see the progression and initial goals.
It is also interesting see how naive I was at the time, jumping right into it without thinking too much in terms of a system (unified guide? really?)... good old days :)
More videos here.
Hope you enjoy, Cheers!
