Pure Data Soundscape Synthesis

I'm looking for two simple sounds/pieces of music, synthesized using Pure Data, with no sampling.

1. Forest Soundscape:
- Use Pure Data to synthesize a forest soundscape.
- Elements:
- Bird calls
- Rustling leaves
- Running water
- Soft wind
- Rain

2. Ambient Meditation Sound:
- Generic ambient sound for meditation.
- No specific elements required, but it should be calming and relaxing.

Ideal Skills/Experience:
- Proficiency in Pure Data
- Experience in sound design and synthesis
- Ability to create natural soundscapes
- Background in ambient music production is a plus

Please provide examples of similar work done.
