Python written in Python, written in Python (warning: somewhat heavy image included)

[Ofnuts]

All done with four Gimp scripts (all in Python of course)

[wavic]

Would you like to share the scripts? Python is heavily used in almost all the graphics programs but I never wrote something

[Ofnuts]

All there: Ofnuts' Gimp path tools downloads (but using them requires some Gimp skills).

• The first four waves where created by path-waves
  
• Intermediate lines are interpolated with path-inbetweener
  
• "PYTHON..." is laid out over each line with ofn-text-along-path (which is the thing I've been working on in the last couple of weeks)
  
• the animation frames are then rendered with stroke-or-fill-visible-paths
  

Added two new tricks to my bag with ofn-text-along-path:

• Using context managers
  
• Making a "factory" (of context managers...) which is incredibly simpler in Python than in Java

That's cool and inspired me to do the same basic thing in pygame (python 2.7). The next step would be to make a second "animation" that is really just flat and stationary, then "blend" both animations weighted more toward the stationary one on the endcaps (so the head/tail are more still like yours, I also just used blocks not letters, but they rotate to stay in line with snake body as well).
