So, with my new domain, having my own wiki, part of the intention is to start a series of tutorials. The immediate focus is some simple tricks in Gimp for programmers, since programmer art generally has the rep for looking tacky and cheap. I don't claim to be an expert designer, but i do try and keep my art standard above a certain level. The first tutorial is a simple button with a bit of shine and can be found here:

Creating a simple button with a bit of shine
- Open Gimp and Create a new image with canvas size 128x128
- Right click the Background layer, and click Add alpha channel
- In the Select Menu -> All
- Select -> Rounded Rectangle ( Set Radius = 50 )
- Select -> Invert
- Edit -> Clear ( or just press delete )
- Select -> Invert
- Use the Bucket Tool to Fill with color #3d3d85
- Create a new layer above the background
- Use the Ellipse Select Tool with Ctrl + Alt depressed. Using Ctrl + Alt creates an intersection with the existing selection created an intersection.
- Select an ellipse like this:
- Use the Gradient Tool with the Tool Options setup with a gradient from White to Alpha
- On the new layer: Start far below the image ( 50 - 100px below ) and drag to a few pixels before the top of the icon, creating the gradient
- Create a new layer between the background and the highlight layer ( Naming layers is good practice! )
- Select Forground Color: #2a2a5a
- Use the Gradient Tool with the Tool Options setup with a gradient from #2a2a5a to Alpha
- On the new layer: Start just above image ( 10px ) and drag to just over half way down the selection
- On the background layer in the toolbox, right click and select Alpha to Selection, thus selecting the nice rounded rectangle.
- Create a new layer directly above background again
- Setup a gradient from White to Alpha
- Set the Gradient Shape to Radial
- On new layer: Start just below top left rounded corner, and drag to just off ( 10px ) the bottom right corner.
- Set layer opacity to roughly 50%
- Create a new layer directly above the background again
- Select the Paintbrush tool
- Change the current brush tool option to Pepper ( yes the green pepper ) and set the scale to 1.70
- Draw the pepper in the center of the new layer
