I'm sure if someone were to develop a better look and submit the
patches on trisquel-devel they would be welcome. Fiurther the R7
alpha is out, so the code base is there to work from if someone wants
to re-theme Trisquel . If people don't have those skills then
becoming an associate member in the hope Trisquel will eventually be
able to pay for devs, web monkeys and graphic designers to do the
work is the next best move for a better look to the distro.
Then there are plenty of other ways people can contribute to a distro
in this case first amongst them being to recruit more users in the
hope some of them will become devs or paying members.
If you're not inclined to any of those then at least consult a
dictionary on the meaning of 'finite' and think for a bit.
