I am looking for a greeting, which gels well with the logo. Their could be two options i.e.
1. Use logo colours and theme the greeting based on that.
2. Use three colours of Indian flag, and style logo and form three coloured clouds etc based on that. Clouds are important, as we are into cloud computing business as well. We do have a parade on this day, with fighter planes spreading tri colours as well. Those are some ideas I had, rest I leave upto your creativity.
