May I ask what effects you used in GIMP?
Oh my, there goes my mouth blabbering again!
-Effects used: Gaussian Blur and Layer overlays.
How I made the Blockland Logo: I Typed out Blockland in a font called "Impact" Then I basically Alpha to selected it then Made a layer underneath, and grew the selection by 5 then Filled it with white. Same with "The game where you build stuff"
How I made the Drop shadows: I duplicated the layer and made them completely black then used Gaussian blur.
How I made the background: I Took a light blue color and black then Made it into a Radial Gradient. Then made a new layer and filled it with a Custom pattern which I then overlaid and decreased the Opacity of. Here is where you can find the pattern:

You can find the Rig Here:

Your welcome, I might make a Blockland Wallpaper pack if people like it.
Oh and I apologize for the Mis-phrasing. As found by RedGajin.
