To some people, they exist as the work they have done, and to others, they are known as a portfolio. Within the confines of Tregonia, they are known as memories. Through out the years and the different eras of website creation by Tim Dickens, various websites have been created that highlight the skills and progression of skills that have been attained. While some were actual sites, public on the web, others were created for course projects through college.
Free free to peruse the memories of Tregonia.
