You just want board graphics and buttons in black and white? If so, i'll pm you my email addy. For a lo-fi version, why not change the buttons to text links?
Since come of those will be semi hard to make into text for example are boarders
as well as a pic can be this big
But text is big and long so that pic would look like this
Which doesn't work to well
Also besides being black and white maybe making them a bit smaller and since they are black and white they load faster(those are 2 fastest loading colors followed by blues)
