BumpTop is not fully compatible with Lion. It will launch, but it will only appear on one Space, not all of them. And when switching Spaces, you get a flash of the underlying documents on the Finder's desktop. It is a shame that Google bought and has let it fall by the wayside.

They've been bought by Google so no more Bump Top for you.

They're now developing apps for iPhone and Android. No mention of this app on their site. Pity.

Does BumpTop use Flash? My MBP goes up to 98 degrees celsius with version. Maybe I'm doing something wrong ...

Looks like their latest version (1.05.2) of the free download is only available from then through today.


Weird. Do we expect 3D desktops in chrome OS sometime soon then?

After following this project since a few years ago, I was very happy to see a OSX version finally come out. I eagerly started testing it to see if I could replace the default desktop but I immediately encountered several issues which are impeding me to switch. I hope the following observations are helpful:

• Font sizes are too big and there is too much text truncation - by default font sizes should be the same as the Finder and it'd be nice being able to customize fonts.
• Stacks expanded view is too small - the default size is a 3x3 icon grid which is too small and one needs to do a lot of scrolling. Possible solution: make the window bigger by default and make it resizable.
• Files on a wall can't be moved to desktop as a selection - when selecting files from the wall and trying to move them to the desktop, only 1 file moves, the rest stay on wall. Solution: Allow moving selections to desktop.
• Expanded stacks don't auto-close when launching files or opening folders - on a expanded stack when opening a folder, the stack doesn't auto-close like OSX stacks. Solution: stacks should always auto-close where appropriate to reduce clutter.
• New Folders aren't placed on the right spot: When right-clicking and creating a New Folder, the folder gets created in the middle of the screen. That's counter-intuitive in a spacial environment. OSX had this issue and Apple fixed it in Leopard. The folder should be created on the spot where it was clicked with mouse or touch input.
• No Spring-loaded folders - this is an excellent OSX feature that is not present on bumptop. The lack of this feature hinders productivity for many OSX users.
• No formatting on notes - notes can't be formatted to have bigger fonts or colors.
• Stacks can't be arranged by date or name. Request: Allow arranging stacks by name, date, size etc.
• No icon grids - the lack of icon grids contribute to the "messy" look of bumptop. It'd be nice if there were grids.
• No labels - Labels in OSX boost usability since one can tag and prioritize items with color. It'd be useful if bumptop had labels.

Other comments, kudos:

• Rearranging icons inside a stack spatially: awesome.
• Big and small icons on the desktop are great, productivity boost.
• Walls: excellent, placing notes there is great, also a clipboard may be nice too, productivity boost.

These are my first impressions, I hope the project keeps improving and some of these observations can be taken into account.

I'm rating it as 4 stars for the premise of the concept even though it's unfinished and in early stages of development. It has a looooooooong way to go to become usable, but the potential is there.

It runs kind of slowly on my PowerMac G5 Dual 2.3GHz. That said, I like the idea but a couple of things about the UI could be modernized.
Why must I click the mouse each time I want to make the icon bigger or smaller? Couldn't I change the size using a drag action on a little handle, or with a slider that would respond to scroll wheel input, or something that lets me bind a keystroke to it, or some sort of clickless interface such as in http://dontclick.it ?
Also John Gruber is right. It could and should be a complete FInder replacement. Whenever you open a folder, it could replace the whole BumpTop, as you are 'inside' it.
Each folder could have different wallpaper (Floorpaper?).
Also, a key to make the mouse 'sticky' such as in the utility Zooom would be great for quickly organizing files.
I do like the nonsquare icon selection tool. Nice. Keep up the good work.
