Well where's the benefit of doing
```php
$avatar = new \OC_Avatar();
$url = $avatar->get("Kondou", 128);
```
instead of just doing
```php
$url = \OC_Avatar::get("Kondou", 128);
```
?

OOP is overkill in this case, as there's nothing to construct, and one only does one thing with an avatar object at a time …
