Microsoft Excel is a program designed to track and compute information, but here I am using Excel as a drawing tool. These drawings are a part of a series that I executed on an irregular daily basis for 16 months.

Each drawing is in a new 'worksheet,' which is automatically set up as a grid. The drawings were made by changing cell preferences for background color, fill pattern, and border styles and from time to time inserting 'comment' boxes and letters or words.
