After another long break between posting, here's my latest effort.

update: here's a shorter version:

;${qw.l m m l l m.[$c++%12]||z}}}@a=(0,splice(@a,0,5," $t "),@a,10-$d%

this outputs an html fragment - hopefully it's browser compliant which probably only properly works in Moz.
If not you should be able to see what's going on...
this might explain what's happening.
