commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

I installed watch and bc via fink and it worked fine. I imagine you could install those 2 packages by hand if you wanted.
A quick hack before going to work -- A readable binary clock
(clumsy, I know, but it works)
H=$(echo "obase=2; $(date +%H)" | bc); M=$(echo "obase=2; $(date +%M)" | bc); echo $H:$Msolaris version:
while :; do echo "obase=2;$(date +%I%M%S)"|bc; sleep 1; clear; done
Scroller* is an alternative to watch, that works fine on Mac OS X. :)
