These are my links for April 25th through April 26th:

• A Primer on Bézier Curves – So, what if you need to program them yourself? What are the pitfalls? How do you draw them? What are the bounding boxes, how do you determine intersections, how can you extrude a curve, in short: how do you do everything that you might want when you do with these curves? That's what this page is for. Prepare to be mathed!
• BBC – Earth – Sheep are not stupid, and they are not helpless either –
