It's always good to see people building stuff - anything! - but many of these are less original, viable inventions and more just plain models. Number 34, for example, is quite obviously not a serious attempt to build a working aircraft. In fact I wonder how he managed to spend so much ($6,400) on such a piece of crap. Some of the other pictures, like the artificial arms, are far more worthy of merit.
