You can make some snazzy graphics with Photoshop using its powerful range of filters. Just open a new image and then do the rest as shown:
If available, you should also use any other 3D plug-ins etc. like Vertigo 3D Hot Text, Flux Photoshop plug-ins,
Extensis plug-in or Ulead Particle Plug-in. These can be used to create great text and graphic effects.
You can also make textures by exploiting the gradient tool on the toolbar and then applying the filters.
