Halloween Textmate

Textmate had a Halloween update that included nice new icons among other things

Then in another update a few days later all the modding got removed.
The readme says -

" >[2006-11-02: REVISION 1324]
"[REMOVED] TextMate no longer pays tribute to human sacrifices, rape, nor does it show a picture of the God of the deaths in your dock -- ticket 945BEB5D"

Awwww. But I have a copy of Halloweenified! So's not so bad.
