1) Install
0.7.1: http://pastebin.com/LPb4FEv4
0.7.0: http://pastebin.com/2kG4V3tB
0.6.0: http://pastebin.com/bR33cXDU
You can use internet card, and command:
pastebin get LPb4FEv4 holo 2) What do you need
a) Diamond Screen and Graphics card (for good resolution). Beginning from version 0.7.0 you can use a golden GPU card.
Diamond processor (just faster; before OC 1.4 it's not important) 
c) 2 Golden memory planks.
d) Internet card (to get program from pastebin)
e) Hologram projector (to preview your creation)
f) other parts, any levels
 
3) What can it do?
This is a simple tool for hologram edition, viewing, saving and distribution (as `*.3d` or `*.3dx` files).
You create hologram in layers. (48x32x48 voxels). You can switch between "Top", "Front" and "Side" projections. The editor can show additional layer as "ghost", for comparison between layers. By default this is layer "below" or "above" current.
Also the editor allow you to use some hotkeys: '~' '1' '2' '3' for eraser tool or brushes, 'Del' to clear layer.
3DX format is quite lightweight (around 1.4 kB for a complex model). Old 3D format is around 19kB per model, but is easier to parse.
 
4) What does this look like?

 
5) I just want to show my model, do I need a full editor tool for this?
To "deploy" hologram (any computer, any components), you cant use small `show` tool:
