How do you say sun catcher in Greek?

There isn't a single perfect translation for "sun catcher" in Greek that captures the nuance of the English term. It depends on what kind of sun catcher you're referring to. Here are a few options, each with slightly different connotations:

* Παγίδα ηλίου (Pagida iliou): This literally translates to "sun trap," which might work if it's a device designed to capture sunlight for energy. However, it sounds a bit less poetic for a decorative item.

* Διάκοσμος για τον ήλιο (Diakosmos gia ton ilio): This translates to "decoration for the sun," which is grammatically correct but sounds awkward.

* Κρύσταλλος ηλίου (Krystallos iliou): If your sun catcher is made of crystal, this ("sun crystal") would be a good choice.

* Κρεμαστό διακοσμητικό που πιάνει τον ήλιο (Kremasto diakosimitiko pou piainei ton ilio): This is a more descriptive phrase meaning "hanging decoration that catches the sun," and is probably the closest and most accurate translation. It's longer, but avoids the awkwardness of the other options.

The best option depends on the context. If you can provide more information about the type of sun catcher, I might be able to suggest a more precise translation.
