The project24 web site offers iCal users a number of dynamically-generated calendars, which they can modify to their own needs and then subscribe to.

You will find a calendar that you can customise to let you know of new books at Amazon.com that match author or keyword criteria that you set. Another calendar allows you to subscribe to a detailed weather report for the country and zip code you specify.

A script that sets your current weather as your iChat status message is also available.

Most useful perhaps is the customisable holiday calendar, which provides much more control of the dates it will track than most of the ready-made, “off the shelf” calendars:

You can also find a customisable TV schedule and a biorhythms chart.

It is a useful site to add to other places like iCalShare and iCalWorld that offer pre-made, non-customisable calendars of all sorts.ical, calendars, customisable, weather, holidays, biorhythms (!), amazon

iSynCal is an app that syncs iCal events, to dos and alarms between two or more Macs without the need for a .Mac account.

It uses the Apple File Sharing feature built into OS X to get its work done and also supports WebDav over SSL, so that iSynCal can automount network volumes.

iSynCal features numerous options, including the ability to automate the synchronisations, as a screenshot of the app’s main window shows:

Because iSynCal reads and synchronizes calendar files based on the open iCalendar standard, the new version (5.5) offers full syncing integration between iCal calendars and those generated by Mozilla Sunbird or the Calendar extension for Firefox and Thunderbird.

iSynCal is shareware (USD 25) and a demo is available from the developer’s web site .ical, sunbird, thunderbird, syncing, synchronization, webdev, SSL, calendars, .Mac, icalendar

iCalViewer is an app that brings your calendar out of iCal and puts it on the Desktop, where it scrolls from right to left as the days pass.

A new version (2.0.6) fixes a memory leak and offers the option to place events at the top of the window.

iCalViewer is shareware (USD 11) although a limited free version is available. You can get it from the developer’s web site .ical events, desktop, scrolling, calendars, streaming, productivity

I like the look of this.

MySync is an app that provides all the benefits of .Mac synchronisation without the need to have a .Mac account.

It allows you to sync your Bookmarks, Calendars, Contacts, Mail Accounts, Rules, Signatures, and Smart Mailboxes between Macs connected on a single local area network.

It uses the Apple Sync engine built-in to Tiger (so requires 10.4+) and configures one computer as the master and the rest as slaves.

The main window shows how it works:

Be default it will only sync with other computers on the network running under the same short user name, although there is an option to “masquerade” as another user if required.

Of course, MySync’s features do not replace all the benefits of a .Mac account. MySync’s developer provides a comparison of the two on its web site:
.

I can read this. If you can’t, a larger table can be found on the developer’s web site.

MySync is currently in public beta, offering time-limited licences for the beta trial.

You can download the beta from the developer’s web site.
