    Hello, thank you for making this! This isn't the main topic, but I just wanted to make a small correction to the sidenote at 0:41.
    It is true that four-bars cannot achieve perfect straight line motion. However, it is possible to create a perfect straight line with six-bars linkages using inversive geometry (that is, reflecting over a circle).
    The Peaucellier-Lipkin inversor cell is an 8-bar exact straight line mechanism which uses that and may have been what you were thinking of. But, it can be optimized to 6 bars, in the form of the Hart linkages and Sylvester-Kempe quadruplanar inversor cells.
    Thanks. :)
