  • I like the idea, this concept as a higher quality image would be a great FP, but it needs to be higher resolution. Should it be svg too? Aaadddaaammm (talk) 18:31, 10 December 2011 (UTC)[reply]
  • Oppose A complex mapping can be thought of as taking two dimensional points in a plane (a,b), to different pairs (c,d). The brightness and colour of each pixel probably gives you what each point maps to. The problem is that this isn't explicitly stated anywhere, and really, I'd expect some sort of key to be provided. I don't think that this image demonstrates any fractal like behaviour fwiw either. I really encourage anyone uploading pictures generated with computer software to provide the source for however it was generated too, just to make it possible to make changes or generate a higher resolution version.

  • Oppose - Fully agree. No hint is given to the meaning of the colors neither in the picture nor in the article. And, of course, no relation witth fractals exist here. Alvesgaspar (talk) 00:04, 11 December 2011 (UTC)[reply]
  • Oppose - Low EV in the article, very low resolution too --Extra 999 (Contact me + contribs) 03:01, 11 December 2011 (UTC)[reply]
  • Comment - maybe it should be part of a featured set with other complex trig functions. See the category on Commons for similar pictures. I think that the axes labels should be larger, and it should ideally not be a jpeg. --Ephemeronium (talk) 14:25, 15 December 2011 (UTC)[reply]
