Here is one approach:

> tmp <- scan(what='')
1:  "#444444" "#444444" "#434343" "#404040" "#3D3D3D" "#3D3D3D" "#3E3E3E"
8:  "#414141" "#414141" "#414141" "#404040" "#3F3F3F" "#3F3F3F" "#3F3F3F"
15:  "#3E3E3E" "#3E3E3E" "#3F3F3F" "#404040" "#404040" "#404040" "#404040"
22:  "#3E3E3E" "#3D3D3D" "#3E3E3E" "#404040" "#414141" "#414141" "#404040"
29:  "#3E3E3E" "#3E3E3E" "#3F3F3F" "#3F3F3F" "#3F3F3F" "#3F3F3F" "#3E3E3E"
36:  "#3E3E3E" "#3F3F3F" "#3E3E3E" "#3D3D3D" "#3B3B3B" "#3C3C3C" "#3B3B3B"
43:
Read 42 items
> tmp <- factor(tmp)
>
> tmp2 <- matrix(as.numeric(tmp), nrow=6, byrow=TRUE)
>
> image(tmp2, col=levels(tmp))
>

But the image is pretty gray.

Hope this helps,
