Warp is a preference pane that allows you to use the mouse to switch between Spaces rather than using the keyboard.
Warp offers the ability to display a live preview of a space when you move the mouse to the edge of the screen, allowing you to see what you have on another space before actually switching to it. Clicking the preview will then warp you to that space. (Enable this feature by checking the option "Click screen edge to Warp" in Warp's preference pane).
Warp is available free of charge, but donations are appreciated and assist in support and development.
Version 1.2 Beta 1 includes a couple minor bug fixes as well as a new floating pager that gives you constant access to your spaces. The pager shows you a live preview of each space; clicking on another space will switch to it. Visibility of the pager can be toggled with a hot key.
Added a floating pager that allows rapid switching between spaces.
Click-to-warp floating window no longer appears when dragging items.
Fixed wrapping around a single row or column of spaces.
The Warp helper application now automatically relaunches when updating.
PIZZACAKE The floating pager HUD makes Spaces worth using again. It's a small visual overview of all the spaces, I keep it in a corner of my screen so I know where everything is. Click on one of the boxes takes you to that space. A brilliant idea! A few minor visual bugs to be squashed but still very usable. Thank you. (Version 1.2b1)
ROBERT COOGAN I agree! This struck me at first as kind of useless...adding a unwanted feature. But it has really gotten me hooked. I definitely recommend it. (Version 1.2b1)
CARTERA This app is perfect! It is a feature that should have been built in, and is implemented perfectly as well us beautifully! It makes me use spaces! (Version 1.1.1)
ASMEURER I also thought of another good feature idea. It would be nice if right-clicking on the previews would disable them so I don't have to go around them to do so. This way, I could have the delay time set to 0 seconds with no modifiers set without too much annoyance.
Also, I noticed that the version number is one behind, so it thinks there is an update all the time, but the feature set clearly matches up with the current version. (Version 1.1)

GHARTNESS I don't get it. At least not from this description. Why aren't the hot corners that os x gives you just as good? (Version 1.1)
MATIEMAN what this does is it switches to the space next to it when you click there.
eg. if you click on the left side of the screen, it will switch to the space to the left of the one currently active. (Version 1.1.1)

FELINITY ok, just noticed this; I only have horizontal spaces, so i'm only going left and right, not up and down. yet, when I hold my mouse at the top or bottom edge, warp still warps my cursor to the other side - obviously without switching spaces. kind of annoying. (Version 1.0.1)
I do have a feature idea though; instead of either disabling or enabling warp on dock/menubar edges, how about making it so that it'll only switch spaces when you're not moving your mouse around on the dock/menubar. Ie, it'll only warp if you're holding the mouse still, rather than browsing the dock or menu.
This is one piece of functionality that Apple should have included in Spaces right from the off.
My only criticism is that its very easy to jump two or three Spaces when you're trying to move only one.
It would be nice if it only automatically moved you one Space and then you had "push" against the side of the screen again to move to another Space. (Version 1.0)
