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
"new post"
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)
