You might have noticed the colourful sketches on Google's homepage. These fun versions of the Google logo celebrate different people, events or special dates. These are designed by 30-year-old Google Webmaster Dennis Hwang.

Now, for the first time, students in Singapore have a chance to come up with their own doodle for Google. The company is inviting artwork based on the theme 'Our Singapore'. The public can vote for the doodles they like the best. The winning entry will then be shown on the Google Singapore homepage for a day, to be viewed by millions of people.

Meanwhile, here are some tips by the original doodler,Dennis Hwang, to help you create your best work:

1. Make sure your design complements the shape of the letters in the Google logo, but don't let that restrict your creativity.
2. Experiment with different media to see which one works best for your design (you can even create your doodle on your PC).
3. Don't over-complicate your design – simpler images often have the most impact.
4. Remember that your design could end up on the Google homepage, so imagine how it will look on screen.
5. Remember to use color well and think about how it interacts with a white background.
6. Avoid commercial or copyrighted images.
7. Think outside the box – try to create a doodle that's different from your classmates and hasn't been done before.
8. Feel free to use the space behind and in front of the Google letters, but try to maintain your design's overall balance.
9. Have fun! "Doodle 4 Google" is all about creativity and enjoying designing fun things. Think about how you want to change the world.
