Sketch on Skype with whiteboard add-on IDroo
Skype's great for chatting, but it could be more collaborative. With the IDroo whiteboard add-on, you can communicate visually.
When you really need to show and not tell, you'll find the IDroo a welcome tool. Idroo is Skype's version of a whiteboard. You can use to invite Skype users to a brainstorming session or to give a lesson to a mad scientist in training.
Each participant must install IDroo. Once they accept your invitation to the session, they will see your scribbles appear on the board in real time. Anyone who's ever wondered what a slightly elongated cube looks like can look at the board and wonder no more.
The only downside to IDroo is that I found the controls slightly awkward. If I were using a tablet with a stylus pen, then that would be different. But on a PC with a mouse? A bit tricky.
IDroo is free for personal use. For educational use, it costs 6 Euros for one month, 12 Euros for three months, or 40 Euros for a year. Commerical use costs 9 Euros for one month, 18 Euros for three months, or 60 Euros for one year.
