Oh I see, well you could do something very similar in photoshop, I've done stuff like that before.

Could you please explain how? (either photoshop or 3d max)

And the list goes on. Just do a little searching and you can find it quite easily on Google. Photoshop Crystals. =)

Here I only used: polygon tool, free transform and blending modes. I started with making one sharp spike, I duplicated them 6 times, did free transform on every of them, then put them all to screen, then merge them all, copy the layer, put it to screen again, copied, free tranform, copied, free transform, color balance, add text and this is what I got.
