Revelation is a very visual book, since John was told to write what he saw.  He did so in great detail.  One of the assignments in this study is to draw the events as John saw them.  I can’t draw life-like drawings, but I can draw schematics since I have a mathematical / engineering background.  In retrospect, this turns out to be a great way to visualize the book of Revelation, since it forces you to focus on just what is written, avoiding any extraneous interpretive detail that a detailed drawing would add to the text.  Below are my drawings.  Click here for a zip file containing all the images in higher resolution.
