This paper by Vi Hart and Henry Segerman has some interesting hand-drawn images that cry out for a treatment with your favourite TeX-friendly package. I like the concept of throwing up one's hands and saying 'forget it; hand-drawn images it is', but it's just as cool to see such interesting figures done by code.

Figure 1 c) is easy (for those in the know), figure 2 (or some minor variation on it) is do-able, but the 3D model of the cube with the appropriately perspectivised images on faces could be challenging. Figures 3 and 4 should follow from figure 2.

To give a concrete question:

Can figure 5 from the linked paper be generated programmatically? It seems completely systematic to me.

    No way should this be CW. It's going to take some serious work to make those (IMHO) and whoever attempts it should get their dues in rep. – Andrew Stacey Apr 30 '14 at 4:10

    @SeanAllred - thanks for the image! – theHigherGeometer Apr 30 '14 at 4:14

    While I understand that it's ok to have some "how can I draw this fancy picture" questions, this one doesn't seem to be reasonable at all. The figure is not suitable to be drawn in any way but by hand or in a professional 3D software. However, TeX is not such a software, not even with TikZ or PSTricks. Therefore I think the question is off-topic. – yo' Apr 30 '14 at 7:14

    @vonbrand - definitely not looking for a hand-drawn look here, but a clean version with the same information. – theHigherGeometer Apr 30 '14 at 7:49
