I intend to run through all of the capabilities of Sugar, including
animations, videos, and TA Portfolio. Today I am fixing my set of
Turtle Art icon tiles for TA 51. Tomorrow I will post some of my
Turtle Art programs, which you can walk through. In the meantime, here
they are in Logo:

Constant acceleration:

Silent Thunder (默雷/धर्ममेघशब्दगर्ज/دھرممیگھشبدگر ج) is my name
And Children are my nation.
The Cosmos is my dwelling place, The Truth my destination.
