I created these digital images 1974, 1975 and 1976 using an Amdahl main frame computer, with output to a Cal-Comp pen plotter.



The book is divided into two parts. The first part is images based on mathematical formulas

applied to four surfaces of a cube. The whole process began as a challenge from an instructor based on my response to an assignment. My original solution had been elegantly simple; his challenge was to increase the number of

variables.



The second part is figurative images, based on line drawings that were digitized on a drafting table modified with internal sensors to record cursor movements. This was a result of

reimbursement, using ‘computer dollars’ by the faculty, for lost photographs which allowed me continued use of the computer even though I was no longer a student.



The figurative drawings became the basis for a series of paintings and have been documented in a book, Night Visions from Laputa.



The book was originally compiled as a 35th

anniversary project in 2009.
