Hi Jonathan,
The 3D chart thing shown above is a sample made my @markliddell and myself ( @cwoldhuis ) as a demo of how to create the 3D art. The creation of the art can be done a number of ways, this one was mostly measurement and perspective drawing, but later we used pythagoras and trig to determine actual lengths. See the video of the creation to see how we created it.
Overall the students created about 15 different drawings depicting various forms of data – all focused on changing perspectives.
Regards
Chris :-)

For years I’ve wondered how the size of SCHOOL X-ING, painted on the street, was determined to best be visible to cars as they approach it. Lots of variables. Was it just experimental then standardized or was a computation done to produce the best result.

Thanks for sharing the C-Rod faces. A really great lesson to inspire number talk. Also I have to laugh at the cobbled together document camera for only $2,500 :) Last I checked IPEVOs were selling for $70 (well $100 if you want the extra stand)

I’m intrigued by the 3D charts thing, but I don’t get much insight into how they were made. Is it something about setting the angles right? I need some more information.
