Just seems like a good idea to make a lot of money with yet another of these "1,000,000 pixels" sites.    The finished bus will be an absolute mess, with random text strewn all over it and almost impossible to read.

If you wanted to do some good, raise some money and print ONE big sign on the bus just advertising Bitcoin in general. 

I took both of your suggestions, and made one big bitcoin ad.

฿0 out of ฿691.20 for one big bitcoin ad on the back right side of the bus -> 1MjyWLY1Rvx7rtqKwymA6Mo1gXF1UaFB8G

This example has just one big advertisement, not hundreds of small ones. There is no comparison between your project and the above bus.

Maybe you should consider just making  one large advertisement, on one side of the bus only?

I hope Im not being argumentative here, but I would propose only advertising on the right hand side of the bus. That will enable you to advertise on two buses for the same cost.

The right hand side of the bus, has more visibility to people standing at a bus stop. Many people play with their phones while waiting at bus stops. The bus arrives at the stop and takes on passengers. All the other people standing at the bus stop will have the advertisement right in their faces. They can see the ad, scan the QR code and browse directly to the advertised site.

I've just transferred 3.456 BTC (0.5%) of the required amount. Now we just need 199 more donators 

In the event that not enough people chip in, feel free to transfer the money back to the sending address (1Fv6HW...) :-)

These buses look really cool. I might consider buying some pixels. 

I am in awe of the great response this idea gave.

FYI I added PayPal and Laybit as possible donation methods for the Big Bitcoin Ad.

We still need your help to make this happen.

I hope anyone uploading graphics is uploading properly formated CMYK, fully vector images (.eps or .ai). Anyone uploading raster jpegs and tiffs and gifs will be sorely disappointed in the result!  And if you don't know what vector means, you shouldn't be uploading artwork for publishing

You just said it better.
