Download theme http://ekopapers.com/os.htm unpack if nesesarry and copy to Ur mobile to folder Application Data\Home. U should copy xml file and directory too.
I used Symbian phone (Nokia 6600, S60v2) and now Im useing Windows Mobile 6 smartphone (Samsung i600). Both are great but I prefer Symbian because its more intuitive for me.
Samsung i600 support themes. Sometimes they required external plugins like Facede or Fizz Traveller. Check landscape (320x240 Smartphone) themes for i600 or Motorola Q.
Just search Windows Smartphone games (landscape). U can use emulators too (GameBoy, NES GameGear etc.) Install Java emulator (Jeodek, JBedMod3D) if U want play almost any Java games
