A guilty pleasure for quite a few people here: LEGO. So far, one could've seen the silliest things made with LEGO, short movies, recreations of scenes from normal movies, and screenshots from actual games! On the website Flickr, we can see a number of classic games recreated using LEGO bricks, including: Castlevania, Contra and Metal Gear. While not based on the MSX versions, they are still fascinating to see.
