    Link: TED Talks: MIT Working On 4-D Printers - The fourth dimension is one where objects can reconfigure their shape, like proteins that fold into different shapes.

    The kind of thing this guy is dreaming of is light years in the future. How does the 4th dimension relate to this presentation? Is it because this stuff is only possible in the future, and time is the 4th dimension?

    so you assemble something that then assembles itself into the shape you told it to go into when you designed and assembled it to begin with? not going to lie, that seems very pointless in pretty much all applications

    I refuse to acknowledge time as a legitimate fourth dimension for purposes such as this. After all, ANY sort of construction will have a temporal dimension equal to the length of time between when it is built and when it falls apart.

    A true four-dimensional construction is an object that extends into hyperspace, such as a tesseract. At present, such things don`t exist outside of science fiction and theoretical mathematics.

    This was disappointing... I was expecting some progress towards the Singularity.

    Impractical, not cost effective, and disappointing. Perhaps one day.

    I happen to agree with most people here. At best I think of this as a prelude to better technology, but right now it just seems like they`re trying to make it big seeing as how 3D printers got big.

    I watched this and all I got out of it is that I know very little on this subject and I don`t really care to know more.
