I are not the author of these themes but i have just revised the "Ater-ice-theme-pack " of the author BlueScorpio_7 (Solisx7):
I added just gtk2 themes SlicknessS :
You extract archive and extract gtk2 SlicknesS themes in HOME/.themes.
1. SlicknesS-Ater-ice + Slickness_Green
2. SlicknesS-Ater-ice-black + SlicknesS-black
3. SlicknesS-Ater-ice-blue + SlicknesS-blue
4. SlicknesS-Ater-ice-hybrid + SlicknesS
Thank you to authors of these icewm and gtk2 themes !
