I only recently got a Wii U and I've really been enjoying Mario Kart 8. This little model of one of the trademark karts, by Cecilie Fritzvold (cecilihf), is accurate to the game and reflects all its signature charm. The photo-editing is top notch as well, but I think my favorite little detail is the banana peel constructed from three whole banana pieces. Banana-ception?
UPDATE (4/23/16): Here's another Mario Kart MOC from the same builder, this time it's Yoshi on a bike!
The Yoshi design is very similar to cecilihf's green Yoshi that we blogged a few months ago. Oh and check out that green shell - good stuff!
