That looks likea great LCD with a fairly reasonable price tag (would be nice to see a lower P+P).
One request I do have is the supporting code isn't well documented. It's hard to understand how, for example, to draw from pixel to pixel or maybe a line for example.
Can you provide any additional code?
[edit]
Oh in addition, have you considered making some kind of chassies with some kind of connector cables? It would be nice to be able to setup more perminant versions of your products.
Cheers
