Mausimus came up with a really clever conversion of old 2D Sierra adventure games to 3D using a 2.5D camera style (used in modern games like Little Nightmares or It Takes Two) and a voxel engine to keep things blocky and aliased. I think this is really excellent idea – probably the best ‘modernization’ of this style of old game.

He also has some other interesting code projects such as shaderglass.
