Naturally I think my Dragon Curve is the most accurately drawn on the net:
It’s better than the top few hits from Google images anyway.
More examples and code at the new Curly Logo Gallery.

1. Please add timings to the Gallery, so that (e.g.) we can gauge whether to put the kettle on for ‘ldragon 2 13’.
2. Is it worth getting involved in the JavaScript implementation world? I bet this language could go a lot faster.
3. What happened to % ?
4. would Curly Logo be better if the turtle coordinate system had its origin in the centre of a screen pixel?
5. Should the dragon functions divide ‘size’ by 2 when recursing (so ldragon 128 7 is ‘about the same size as’ ldragon 128 2) ? Or maybe sqrt(2) ?
6. What else is new? Can I quote yet?

7. I would prefer s/100/57.3/ for the sin/cos graphs.

Some nice dragons.

7: Quite right (this occurred me just after I’d set the images in PNG and was too lazy to fix it). Done.
3: I removed % because I considered it: a) a silly symbol; b) ambigous. Please use remainder instead. mod not yet implemented.
4: Dunno. For some of the “pixel perfect” stuff, yes. But for general doodling a pen width of 2 looks better, and with that pen width it looks best if you start at a corner. Actually I just tried setpw 3 and starting on a pixel centre and that looks pretty good, I might go with that in future.
5: Probably. It’s faster not to and it’s also what Abelson and diSessa do. The current dragon definitions are not “heading modular” either.
6: Can you quote what? [1 2 3] is a quoted list and always has been, but, new, now you can test for membership with member?.
Nice dragons: how amusing, someone else drawing fractals on their own obscure implementation of Logo!
