Some quick and dirty contraptions that I cobbled up just for fun.

As makers, random serendipity is very precious to us, as it represents an excellent opportunity to broaden our horizons by trying stuff that otherwise would not have crossed our minds.
This project was spawned by a chance encounter with an art museum curator during my stint in Edinburgh. The idea was to create a tool to generate Secret Portraits , also known as Anamorphosis , to make some cool merch that would support the operations of the museum....
This is a tool I developed to assist us at the Cambridge University Spaceflight Club to design a patch antenna for telemetry.
It is intended only as a very crude estimate, as I have absolutely no idea how accurately I selected the underlying formulae.
