This site is laid out so viewers can click on the up and down arrow buttons to get frame-by-frame navigation on most pages at 640x480. At 800x600, the pages will look reasonable at full screen, but the browser window really needs re-sizing to 640x480 scale. Use at least High Color at 640x480 as I have optimized the GIF files for quicker loading, and frankly,  some do not look their best at 256 colors.
