There are many things that happen in at k23 Productions.

Firtstly the brand new app dotWidget is almost finished, the newest version is RC2. It's an app for having 'widgets' on your desktop. I hope everyone knows what widgets are Currently it only supports VBScript, but more scripting languages will be added shortly. You can of course make your own widgets for it. It's really easy. You can also upload your widgets to the main site so anyone can download it.

Then we have a whole new release of the good old s:Kimo-Jo which is now Bar None: Zen. It's a tiny application launcher designed to take up as little space as possible on your desktop, while still providing a vast amount of functionality. The new Zen release supports skins and gradients so you can make it look much better than the old s:Kimo-Jo. You can also extend its functionality through the use of both ActiveX and scripted command addons.

And of course there is also iceFire 2.2 which hasn't been updated for a long time but still is useful. The basic design of it follows that of the BeOS Dockbar. The main features of iceFire are: Title Bar - allows access to various system functions and your files, Shelf displays a digital clock and Shelf AddOns, which are small code modules written by developers that appear as icons in the shelf and The Dock can host any number of 'docklets' which can, in turn, host any number of plugins, can be rearranged within the dock and collapsed to save on screen space.
