Talk:Double bubble theorem

Accompanying photo
I'm very glad that there's a photo that accompanies the article. Most folks appreciate abstract ideas better when they can visualize them. Good illustrations are hard to come by.

However, this photo does not show a minimal surface. The smaller bubble should push/bend into the larger bubble, but the illustration shows a flat surface between them. I mention it because this is a common misconception, and the illustration perpetuates that mistaken mental image.

Does anyone know what software was used to create the illustration in File:Double bubble.png? Thanks, 24.240.67.157 (talk) 01:33, 14 June 2015 (UTC)
 * I don't know, but maybe a better question is: what software can we use to get a good image that doesn't have this problem? I agree that it is a problem. —David Eppstein (talk) 02:33, 14 June 2015 (UTC)
 * Update: I replaced the bad illustration by a prettier photo. The two bubbles in the photo are quite unbalanced in size, making it more obvious that the surface between them is not flat. —David Eppstein (talk) 04:53, 14 June 2015 (UTC)
