ere, "finish" is an umbrella term for all that you do with your logo after you've finally decided that both the visual and the text are ready, sit in their proper places and have their proper colors.  Finishes include various decorations such as surface textures, drop shadows, highlights, gradients, transparency, etc. This category is, all in all, a sign of modern computerized technologies---you couldn't see a drop shadow or a marble texture in a pre-desktop-publishing publication or, God forbid, a logo.

People generally believe that cool finishes is what makes their graphics professional.  Far from that.  Finishes may give, as the word implies, a finished appearance, but no amount of drop shadows will improve a logo which is designed poorly with regard to its shape or color.  Strictly speaking, finishes do not represent a separate media, so in applying them you can refer to all the principles I've tried to outline above.  Feel free: Once you've made a cool thing and you know what makes it so cool, you're unlikely to spoil it with wrong finishes.  (Although this happens time and again.)

Speaking of tools, the stage of applying finishes is where you quit your vector drawing package and export your creation into Photoshop or other painting program.  (To be fair, Corel Xara is one vector package that's capable of making transparency and some sort of drop shadows, thus almost eliminating the need to edit the exported bitmap.)  For a designer, finishes are primarily a technical issue; it's a matter of learning and applying certain tricks---of the sort that is taught a lot on web design related sites and in magazines.

So what do we have in our logo to fiddle with?  First of all (although this is more relevant to the Forms section), note how the dot above the "i" comes close to the point where the squares' corners converge---but does not coincide with it.  One general form-related principle (looks like I've not covered it so far) is that lines and points that come close enough tend to "snap" at each other in the urge to reduce the overall number of elements in the picture.  So let's move the text a bit so that the dot above "i" covers exactly the point of convergence.  (The letter "i" is really a favorite for logomakers, by the way.)
