PokerZebra is the working name for a Texas Hold'em Poker Odds Calculator for Mac OS X. You can download PokerZebra 0.4 here. Leopard or Snow Leopard required. I suspect it will only work on Intel macs, but I could be wrong.
You can now evaluate a hand against an opponent who has any two cards, by using the word "random".

This was the hardest part of this little project. It required me getting familiar with running a cancellable task in the background in Objective-C. I usually program in Java, so my Objective-C skills are basic. Cancellable background tasks that provide ongoing feedback in the GUI is an advanced topic in any computer language I'm familiar with, so it has been a steep learning curve for me. (Note to self: maybe it shouldn't be an advanced topic? Maybe language designers need to make this easier?)
Once I've fixed any issues that arise in this update, I can add specific ranges, such as AA (any two aces), 77+ (any pocket pair 77 or higher), or K3+ (any hand with a king and a 3 or higher).
There's also an app icon, created by Rob from the Netherlands:

Here's what you need to know:
- This works on Intel Macs running Leopard (Mac OS X 10.5) and Snow Leopard (Mac OS X 10.6). Perhaps I'll be able to add PPC and Tiger support soon. No promises though.
- Specific hands (eg "Ah Kh") are supported, as is random hands ("random"). Currently other ranges of hands are not supported. This will come soon.

Works perfect on my PowerPC G5. :)
@Fabian,
are you sure it is giving your the correct odds on your PowerPC Mac? Try the example in the screenshot in this blog post and see if you get similar results.

Steve

Thank you, sir :)
Oh, sorry Steve. The odds in percent change every second. Weird
@Fabian,
The odds change every second by design. It takes a long time to evaluate against a random hand, so PokerZebra keeps updating while it completes the evaluation, so that you can at least see a partial result while waiting.
