Scribblar allows you to see in real time what font needs to change, where your client wants the sign up bar to go, and whatever nit-picky things that could cause a designer to go crazy. Visitors can chat via audio or the minifeed to communicate what changes they’re trying to make.

Scribblar is as close as you can get to remote-PC for designing purposes as one can get. And for being a free, powerful, collaboration tool, its sure to be of use.

Splashup looks and edits similar to Photoshop, but lacks some advanced features (vanishing point, a couple layer effects, fonts, etc.). Though it lacks those advanced features, it does contain layers, gradients, and the shapes tool to help you get started. Create a new image from scratch or upload your own from your computer. When you’re done, simply save it to your computer or any major image sharing website.

Certainly no replacement for Photoshop, but comes in handy when you really need it.

Flowplayer users progressive downloads (this is how YouTube does it), provides thumbnails for videos, protects against hotlinking, and multiple size viewings for your video. Want to change the design and layout? Flowplayer has customizable skinning options that can be changed easily. Full list of features can be found here.

Flowplayer is an easily customizable, easily skinnable, feature rich media player while maintaining a very lightweight size. You’ll be sure to impress your clients with this web application, and maybe even yourself.
