Taiwanese design group KBme2 has developed clever ‘brick lighting caps’, which are connector pieces that plug into your iPhone’s earphone jack that allows you to connect it to any LEGO brick.
This cap allows any LEGO lover to let their imagination go wild with connecting unique LEGO pieces to their iPhone, iPods, or iPads, in any way they fancy.
