I published a OSX Ruby Growl script: https://github.com/lichtamberg/Growl-Ruby-Bitcoin-Ticker
Ruby script for OSX which fetches the current trade data of Mt. Gox and Bitmarket.eu (EUR) and
shows a growl notification if the trade data exceeds a specific up/down limit.
You can justify yourself which limits you want (f.e. notification when last trade was 15 % higher than the last one)
=== Requirements ===
Ruby (think it works with 1.8.7 as well as 1.9.2)
and following gems:
=== Limits ===
Default values are:
up_mark = 1.007
down_mark = 0.993
You can set them in the script yourself.
