How many sketches do you have in mind to show? Do you want to present screenshots?
Do you want to do this in Processing or P5.JS?
If you have screenshots I have some suggestions:
You can have them display randomly, with a name and a brief description.
You could display them in an orderly manner, where you define the order (based on a list, or tag umber that you defined apriori)
You could have a list with links, where each link will open the work of a single student
You can show case 5 at the time
Or you could even have a small video of each project. there is a lib available in processing that allows you to do that.
