I am starting up a social enterprise 'Altus Impact Lab' with two colleagues. We are looking for a logo for our enterprise ([url removed, login to view]). Altus is a latin adjective for deep and profound. We would therefore appreciate a logo that illustrates that we are trying to mobilize profound change, address issues at the roots and/or create deep impact - in other words, a logo that plays with the word deep. Many thanks on beforehand.
