TA Freeware/Public Domain Software

No, I'm not trying to save some money by not shelling out. I'm after some very basic TA software on which to undertake some basic analysis on non-equity price data which I will need to enter by hand. Is anyone aware of any public domain software I can download? Thanks.
I went surfing on Altavista using technical analysis as the search. It's very timely comming across this site as the software became free on December 15th. Also found some other interesting freeware.
