It has three layers, foreground, background and floating layer. There're two color on foreground, one color in background and one color in  floating layer. So it has four colors and three layers.  .

F. 2D/3D, size 20mm*20mm, square, two layers, four color

 

It has two layers, foreground layer and background layer. There're two color on foreground and two color in background layer. So it has four colors and two layers

G. 2D/3D, size 24mm*14mm, rectangle, three layers, three color

 

It has three layers, foreground, background and floating layer. There're one color on foreground, one color in background and one color in  floating layer. 

H. Dot-matrix & 2D/3D, size 30mm*15mm, rectangle, four flips

 

It has one layer. There're two 2D color on surface. Dot-matrix effect lines make rotating light effect. Four flips of 'SECURITY' also make flips like a movie clips which shows each flip in different view angle.
