(This will be the first in a series where I show how I solved some of the issues in making http://osx.iusethis.com/) Iusethis uses a common layout style with one main pane, and a smaller right-hand sidebar. We've made it so it is easy to reuse these sidebar items by putting them in a /sidebar folder in our template directory. Then we can just do stuff like [% PROCESS sidebar/didyouknow.tt %], and presto, you have a box like the one you can see on SQLitemanager for instance. This box was implemented 100% in the TT view, so that it doesn't require anything from the controller. To pick a random number, I use the TT Math plugin like this:

 [%USE Math %]
 [%SET tip=Math.int(Math.rand(10))+1%]

This assigns a number from 1 to 10 to the TT tip variable. Now it's just a simple matter of using a TT switch:

[% SWITCH tip %]
[% CASE 1 %]
You need to floss more often
[% CASE 2 %]
Don't Panic 
[% CASE 3 %]
...
[% END %]

And that's it, really. Hope this comes in handy for someone :)
