It seems cool.

And I must point out that the graphics tutorial in 
http://www.texmacs.org/tmweb/help/tutorial.en.html is outdated(the scheme 
code part).

When I am new to TeXmacs, I try to follow the tutorial to draw the rose but 
failed(not good experience).

I hope someone puts warning there or updates the tutorial. If anyone can 
provide the original tm file, I'am willing to update the tutorial for the 
latest TeXmacs (just need to modify several scheme code).
