What we did was we played around with the graphic tablets to get used to how they work, the graphics tablet is made by a company called Bamboo pen & touch which lets you trace already drawn images or draw new images straight onto the computer, to load it up all I did was I opened photoshop, pluged in the tablet and hey presto, it works.
This is what the Bamboo tablet looks like, the tablet has four buttons on which one is a left mouse click and the other is a right mouse click but I am not sure about the other two.
On the pen it has a nib where the graphite would be on a normal pencil and this is a little bit of rounded of plastic where when it comes into contact with the tablet it makes a connection and the more the little nib goes into the pen, the darker the lines are on your drawing.
Also on the pen it has a rubber (not really a rubber but the same as the nib and it only rubs out) and it has a left mouse click and a right mouse click, so to control the curser you hover the pen about one inch off the tablet and move around.
When I used the tablet the other day I did a test drawing, and this is what my first drawing looks like.
Not really Picasso but its OK for a first drawing.
