For this last one, i decided to use my previous work and add on a 3D solid in my work as my final e wallpaper.
first of all, i had found a colourful cube.
Next, i find a picture of FOM building. then i select pixel on that picture and click Ctrl + X to cut the picture. Then, i click Filter >> Vanishing Point. i used the create plane tool to select the cube.
After that, i click Ctrl + V to paste the FOM building here. Then i use Ctrl + T to resize the picture and fix in the cube.
Then i click OK. Now, the FOM building is appear in the cube. Then, i used the same way again, to paste another two pictures which are E-bee and MMU gate. After that, i change those picture opacity. Then i make it merge visible.
