How can i do this?

[Robson]

Hi. Hope someone can help me out. I am trying to do this to my 3 solid shapes I created in PS. I want to replicate this picture below of 3 blocks. I do not know what to use to accomplish this effect. A brush? Eraser tool? The three shapes have a grey background. Any help in explaining how to accomplish this would be awesome! Thanks.

Three layers three colours use erasure brush to remove parts of each block then use the glass filter on each layer then combine, should work.

and it looks like they used a snowflake brush for the erasure brush

Yep indeed they did.

Thanks Paul. That worked. Yes, was a brush, but I did not you the snowflake one.
