The Breck Chapel burned down about a year after Dad died. Martin Vinik said: "I guess you can take it with you."

Rhomboid - a problem to occupy Collis while work was slow.
Affectionately known as the Magnificent Obsession.
(Also, dome below)

Given an angle and two diagonals, construct a rhomboid - not by trial and error.

A rhomboid is a parallelogram in which the adjacent sides are unequal.

• Let A be 1/2 of the longer diagonal, B be 1/2 of the shorter diagonal.
• Create point D by dropping a perpendicular line from a distance A - (A-B)/4 down to a line that is at 45 degrees from the horizontal axis and runs thru the center.
• Use that as a radius to find point D on the horizontal.
• Draw a line at 1/2 of the angle from that point.
• Where it intersects the circle of radius B is where a corner is. The rhomboid is determined.

A poster created by Nicky showing many of the workiing documents, including the back of a popcorn box. Extra large version	A working drawing that gives a little insight into how he solved it.	The same solution as above with out white out. This is dated 7-25-70. The earliest date is 1-10-70 claiming he had been working on it for 13 days.
