I solved this by making a page Template (not to be confused with Theme, which is something completely different). The template lists all the subcategories of a category, specified in the page metadata, along with the category description and the last 5 posts for each category. This way you can list all the projects on one page and link to the most recent information for each one. Because the category name is specified in the page metadata, you can have multiple CMS pages, for example, ideas, projects or experiments.

Add the template file to /wp-content/themes/<active theme>. To use this template, make a new page, then select the template called ‘CMS’ from the list of templates. The content will be shown at the top of the page. Next you need to add a metadata (also called custom field) to the page, with name ‘category’ and value equal to the category you want the page to show. You might need to edit the template slightly for it to display properly with your theme.

        <?php if(($category = get_category_by_slug($category_slug)) != null): ?>

          <?php $categories = get_categories(array('child_of' => $category->term_id, 'orderby' => 'name', 'order' => 'asc')); ?>
