Thanks to a chance online stumbling across Kiyo's Blog (ok, "chance online stumbling" is more like a link in my email triggered by a google alert for 'google spreadsheet' ;), I discovered this really cool open source timeline widget in the form of a Sample Timeline using a Google spreadsheet. So it was a double bonus for me.. a cool widget and, even better, a great use case for the spreadsheets API !
Now I could have discovered this earlier if I watched everything that came out the developer pages of Google - as this widget was highlighted previously as a
Google Code Sample related to using Google Calendar API.... but Kiyohito Yamamoto saved me the trouble of both recognizing the opportunity and then coding a spreadsheet-sourced timeline... Thanks Kiyo!
