Tony Moreno, a Portland web designer and musician, designed the artwork, titles, page colors, navigation tools, and so on, for ROCO during the summer of 2001. His work was supported by Reed College's NSF-AIRE grant.

I changed the navigation tools in ROCO during the summer of 2004 to make it easier for me to add more essays, modify figures and formulas, etc.. The new ROCO is less elegant than Tony's original design, but iI hope that it is at least 95% faithful to the original.
