Thanks to timboslice for mentioning Gmap4. I am the developer of that browser app.
By my count there are 5 browser apps that I refer to as enhanced Google map viewers. Each of us devs have produced our own version of Google maps on steroids so you can surf maps (including seamless topos), display your data, or display other data that you find online.
In order more-or-less by launch date, these 5 apps are:
ACME Mapper
GPS Visualizer
Gmap4 (Joseph Elfelt - that’s me)
Hill Map
CalTopo (Matt Jacobs)
A few years ago the USGS made very hi-res scans of all (yup “all”) their paper topos. Matt shipped a box of harddrives to USGS and got back copies of those scans for the most recently published paper topo for all of the USA. Of course for some locations the “most recently published paper topo” is rather old. Matt whipped up some GDAL magic to de-collar those scans and chop them into tiles. He is hosting the tiles on Amazon’s cloud and invited me to display them with Gmap4 (where I call Matt’s tiles “t4 Topo High).
Finally here is a project I just started a few days ago to use Gmap4 to display data that (1) is hosted on state and federal GIS servers and (2) shows public land boundaries and recreation features. Here is the top page for this project. OK, time to ’fess up. I’m a software dev, not a web designer.

(The html pages for these public land maps contain a plug for my startup which georeferences land surveys and property legal descriptions.)
One of the next features I am going to add to Gmap4 is the ability to click a GIS feature and see a popup with the attributes for the thing you clicked.

You can customize these links. For example, here is one that displays the very cool New York state bike map zoomed in on a random spot: http://www.mappingsupport.com/p/gmap4.php?ll=42.346429,-76.8...
