The name "TUNES" is a recursive acronym, which stands for "TUNES is a Useful, Nevertheless Expedient, System". The name demonstrates our commitment to build a computing system according to long-term concerns about how computing should be, as well as practical requirements and opportunities of today's computing.
Actually, the "N" used to stand for "Not", meaning that we conspicuously do not strive toward expediency in the restricted meaning of "being good in the short term with overwhelming bad side-effects in the long run". It was transformed into "Nevertheless", to insist on the fact that despite our being attached to long-term implications of our system, we are conscious that to live and survive, we must be strong on short term issues, so that we aim not only long-term utility, but also short-term expediency, in its extended meaning that does not preclude said long-term utility.
Currently, we have the 100% pure HTML virtual reflective logo that you can see on our page. People have suggested or submitted eye-candy logo pictures, and we have been queueing these suggestions and submissions; but we won't even consider changing logo until we have an actual serious code base we can be proud of, that could honestly bear a logo. Otherwise, the project would be all fluff and no stuff.
