It's a little long, but I think you'll like it.
Greg

01) Create a square image. (500x500 in my example)
02) Layer > Transparency > Add Alpha Channel.
03) Select > Select All (Ctrl+A)
04) Fill the selection with black using paint bucket (Shift+B)
05) Select > None (Shift+Ctrl+A)
06) Run the Rule of Thirds Script if you have it and skip to step 11.
(Script is available here http://gimpchat.com/viewtopic.php?f=9&t=427 or http://registry.gimp.org/ where you can get all of my scripts)
07) Image > Guides > New Guide by Percent > Horizontal 33%
08) Image > Guides > New Guide by Percent > Horizontal 67%
09) Image > Guides > New Guide by Percent > Vertical 33%
10) Image > Guides > New Guide by Percent > Vertical 67%
11) Using rectangular Selection Tool (or press R key) and select the first square (1 of 9).
12) Select > Shrink > 5 pixels
13) Select > Rounded Rectangle > 10%
14) Select > Feather > 10
15) Cut out the selection (Ctrl+X)
16) Repeat steps 11 - 14 for the remaining 8 squares.
Image
17) Rename the layer as "Rubiks Frame" and duplicate layer twice. (Total of 3 layers)
18) Load the three selected images as layers. (Ctrl+Alt+O)
19) Resize each and crop to 500x500.
20) Alternate the layers as Rubiks Frame, Picture 1, Rubiks Frame copy, Picture 2, Rubiks Frame copy #2, Picture 3
Image
21) Merge Layers 1 & 2 together, 3 & 4 together, and 5 & 6 together.
22) Right click on "Picture 1" layer and select "New Layer", name layer "Cube" and click on ok. (Pictures don’t show correct name.)
Image
23) Filters > Map > Map object.
24) Map to: Box
25) Click Transparent Background button. (you should only see the checkerboard pattern in preview window)
26) Click Box Tab
27) Set Front and Back to Picture 1
28) Set Top and Bottom to Picture 2
29) Set Right and Left to Picture 3
30) Click Light Tab
31) Set Light to directional
32) Click Orientation Tab
33) Under Rotation Set X= 20
34) Under Rotation Set Y= -25
35) Under Rotation Set Z= 0
36) Click Preview (Now you should see your current cube design)
Image
37) Experiment with the X, Y and Z rotations. (Preview after each change)
38) Click "ok" when you are happy with the preview result. (Can take a minute or two)
39) Turn off the 3 "picture" layers
40) Turn off the grid lines (Shift+Ctrl+T).
41) Right click on "Picture 1" layer and select "New Layer", name layer "Back" and click on ok.
42) Fill layer with background color (or pattern) of choice. (Shift+B)
Note: If using pattern you might want to use the perspective tool (Shift+P) to give dimension to background.
43) Click on "Cube" layer.
44)with GIMP 2.2 Script-Fu > Shadow > Drop Shadow >

but with GIMP 2.4 Filter/Light and shadow/Drop Shadow

Offset X = 25
Offset Y = 25
Blur Radius = 25
Color = Black (Default)
Opacity = 80% (Default)
Turn off "Allow Resizing"
Image
45) Click Drop-Shadow layer.
46) Click shear icon (Shift+S)
X= -250
47) Click scale Icon (Shift+T)
Width = 649
Height = 200
48) Click on move tool (or press M key) Position shadow where you would like it.
49) You can also vary opacity of "Drop-Shadow" layer if you'd like
50) Click links on "Cube" and "Drop-Shadow" layers (Next to eye)
51) Still using the move tool, drag cube and shadow to place it where you'd like.

Like I said, a little long but worth it... I think.
Greg

PS - I'm thinking of writing a script!

Well, I'm working on the tut...unfortunately I forgot to crop each pic to image size, so it took 1/2 hour to render the cube...when I saw the grid in the center of each box face I realized what I did. I am now waiting for it to render with the proper sized layers. It's still taking a long time because my computer is slow.

*edit...phew, finished...after a few goofs and re-do's, lol
Image
I remember doing some of PM's tuts a long time ago, but then I was blindly following with no idea what I was doing. Now I actually can tell what's happening, lol. Too bad the computer is so much slower now that I am faster!!!

That was fun. Finding 3 car images to crop to 500x500 took a little time.

View > Snap to canvas edges made selecting the squares easier. Snap to guides is already in place.

I didn't put a shadow on mine.

Cars
Green = Lamborghini
Blue = Jaguar
Red = Ferrari

I love your M&M's one Rod. NIce.

I buy these chocolate covered pretzels. They come in a box and I found them in the Crackers/Cookies section of the grocery store. There are 6 100-calorie packs all measured out for you in the box.

I put in a Google search for them and was very surprised they showed up in amazon.com. You don't have to get them from Amazon though. I just wanted for you to see the box they come in.

You ever see those commercials where their are a M&M guy and a pretzel guy sitting together and the M&M guy says to the Dr. ok lets get this over with...and the pretzel guy looks at the M&M guy and says...im not too happy about this either ya know! =)

Funny piece!
