I was at Sasana Kijang KL gallery and they have some really cool installation. One of them which stand up among others is this spherical projection installation.

Different from most projection mapping i have seen, which project from outer to the object, this one project inner inside a spherical object. Even more amazing, it required only 1 projector and the entire sphere is filled with graphics without gap.

A quick Google search shows that it is done by a UK company called Pufferfish. You can see BNM logo is appear in their client list.

I have no idea how they do it. I think it is a propriety technology.
