There's a certain charm to Minecraft's default visuals, but it can also be argued that without help the game looks like arse. When you see jaw-dropping screens from the game, like these Game of Thrones pics, those slick graphics come courtesy of tricks like rendering, where what were once basic blocky tiles are passed over and given effects until they look like something you'd actually expect on a PC in 2013.
Here's a great example by Sandra/sickyouth that takes a subject that should be utterly pedestrian - a simple table, chairs and window - and makes it look like Minecraft 2027. No epic vistas or enormous projects here, just the basic stuff you see all the time in the game, only here, it's nicer.
