  <description><![CDATA[This is a collection of common example surfaces from classes in multivariable calculus. Students in these classes often find it difficult to visualise a surface given the equation for it, but these models will make it a lot easier to see what's going on! They show the contour lines when you slice each surface with horizontal planes, together with eight radial curves. The <a href="http&#58;&#47;&#47;shpws.me/mNDp" target="_blank">small versions</a> of the surfaces are available as a set, and the <a href="http&#58;&#47;&#47;www.shapeways.com/shops/henryseg?section=Calculus+Surfaces" target="_blank">large versions</a> individually. These are currently in use at Swinburne University of Technology in Melbourne, Australia.<br />

  <description><![CDATA[Such a great idea. These models should make calculus surfaces much more accessible for students by giving a visual and kinesthetic perspective. What are you using to support the hyperboloids? I can't quite make it out.]]></description>

  <description><![CDATA[Congrats , They look amazing. <br />
What size is the diameter of the wires in the large ones ?  <br />
I am considering printing a wireframe statue. <br />
