I like when a logo is not only made of the letters of the product. The flute / road-sign / jack-in-a-box could be really nice, and you could have versions of the logo with and without Tox written below/aside.
Also, looking at the PDF, the 7th logo made me think about a beetle (don't know if you guys can put a meaning on that) or a turtle, and the 16th could look like a nail targetting a cross, helped by the circle if it was more encircling the T. The last one is too much like controllers buttons.
I think you can draw a snake (python) head with the letters though, but it will need more talent than I got:

:v:
I'm not sure we'll get availability for these; so maybe we should just go ahead with one of the ones we already have ready (sent out to the mailing list in round 2).
@hpk42 is in touch with Gero who could do some more design work. When I am back from London I wanted to see if we can get anywhere with this.
Please make it look decent on favicon size, that's my top concern, I hate complex logos. Also if you make it use a single color it will be cheaper to make nice transparent sticker for our laptops.
Also avoid doing the kind of work Atlassian and JetBrains did with their re-branding ;)
