views - linking blocks to other blocks dynamically on the same page.

Two students from my Web Programming/Drupal course came up with a Views question that I'm not able to figure out. Linking blocks to other blocks dynamically.

They want to have a block showing a list of vocabulary terms. In this case types of Recipes. On the same page they want to have a block showing all the recipe titles available for any category that is selected. Then, when the user clicks on a Recipe Title the full recipe displays (they already solved this part of the problem).
