Tom Mangan just won't stop creating great things with Google Maps! So far he has brought us Track the Space Shuttle, Blackbird Spotting and Area 51 Historical Photos
The Space Shuttle tracking tool has just been updated to include his newest creation - TLabel:
TLabel allows you to embed any DOM object inside Google Maps. It's especially useful if you need to show an infoWindow but don't have enough content to fill it. A TLabel is only as large as it needs to be.
TLabel also enables you to define mouseover events for your map. Simply place a transparent label where you want the event, and handle the onmouseover as usual.
Check out this site for more information on using TLabel when building your Google Maps mashups.. It's a great feature of Google Maps viewing! See it in action here.
