I used the Matter app to create a set of cubes, or blocks, that are wrapped with an image that I created previously using iColorama and Paintstorm. Then I used iColorama to blend a handwritten letter as background to the cubes. I created a drop shadow for the cubes in iColorama.
I started with this image I made previously. You can see how I made it here.
I opened the image in iColorama. I used Form/Warp to make it into a square, and Form/Crop to crop it.
I used Adjust/Exposure and set the brightness slider to high to create a blank white canvas. I opened the blank canvas in the Matter app. I used the first Primitive Object in the Wrap style with Shadow turned off, and imported the square image I made. Then I made one cube, then another (using "add another object"), then another, until I had five. Each time, I used the Mask tool to remove a portion of the newly created block, to make it appear as if some objects are behind others. When I was finished creating all five blocks, I saved the result to my camera roll.
I opened the cubes image in iColorama. Using Style/Threshold, I made this black and white image, and then I used Brush/Paint with black paint to fill in any gaps. I saved it to my camera roll. I will use it as a brush mask later.
I again opened the cubes image in iColorama. Using Effect/Blend, I blended a newspaper image over the blocks. I imported the black and white image I had saved previously as a brush mask. Then I inverted the mask. The result is that the blend applied only to the cubes and not the background.
This is the newspaper image I used for blending, above.
Now I un-inverted the mask and used Effect/Blend to blend a handwritten letter over the cubes. This has the effect of applying the letter to only the background and not the cubes. I applied and removed the mask.
This is the letter that I used for the background.
Now I opened the black and white image in iColorama. I used Effect/Blur preset 2 to blur it. I adjusted the Radius slider to get an appropriate amount of blur so that I can use this to make a drop shadow for the blocks. I saved this to my camera roll.
Now I opened our work in progress (the image of the cubes against the letter) in iColorama. I imported the unblurred black and white image as a brush mask, and then I inverted the mask. Then I used Effect/Blend to blend the blurred black and white file, that I saved previously, over the image, and I offset it by dragging it with my fingers. This created a drop shadow.
Because there were white edges around the cubes, I used Style/Edges preset 1 in Multiply mode, with a small size, to darken them.
Finally, I used Preset/Border 2 and 3 at low radius and low opacity, for a bit of vignetting.
