Media Molecule Technical Director Alex Evans held a lecture at Siggraph 2015, showing the journey of the engine used to make its upcoming PS4 exclusive Dreams, including all the failures that led to the successful final result.

The lecture has been repeated recently at Umbra Ignite in Helsinki, and the great thing is that this time it has been filmed, and we can see it all in motion.

Interestingly, even the failed attempts looked really, really good, at least in most cases.

Evans also mentioned at the end of the lecture that he showcased the failures in order to encourage other developers to try unconventional approaches like Media Molecule did, and that he believes that there's "massive untapped potential" in compute shaders and in the current generation of hardware.
