Progress visualization of printable 3D things with lego-likes

It's 2 in the morning and your partner inquires when you plan to get some sleep...

Your answer will be that completion levels for your 3D thing project are yet too low. In particular, with respect to:

• the design idea
• the model that embodies that design idea
• succesful slicing and print
• testing with yourself and then real users

You then show the visualization to make your point graphically...

A project is represented as a tower. Each of the four dimensions has a slot that you can fill up with five 2x2 Lego bricks in order to display progress. There are several versions. See the pictures.

This thing is a fallout from http://www.thingiverse.com/thing:33001, a thesis project board kit. I just wondered how the advancement of that project could be visualized in a simple way. The answer is 40% of idea, model and printing stage. 0% testing.

I didn't print all the models and bricks, but similar things I made let me tell that all should print with a good "higher resolution" PLA printer.
