A software that I can decorate my home with it.
honestly the absolute bestbest one is sierra home architect. they dont make it anymore and it is not compatable with windows vista :( everything is in 3D and you can customize absolutely anything! if you dont have vista you might be able to get it on OKorder for pretty cheap..
You may use Windows Vista in the middle computer and arrange windows ME all around it like petals of a flower. You will need about 9 such computers with windows ME if you have a big room to decorate. Use computers with Linux as the stems and the branches and computers with Unix or Windows 2000/NT as the leaves. You need to hang all these computers on a wall.
