You can make most pulmonic voiced consonants, except laterals, trills, dentals, and retroflexes, so /m n ɲ ŋ ɴ b d ɟ g ɢ ʡ ʔ ɣ z ʒ ʑ β ʋ ɹ j ɰ ʁ ʕ ɦ ⱱ ɾ/ are all possible, as well as all vowels. If you're really quick with your mouse you can then make pretty decent sounding words using any of these sounds. Some relatively easy ones I managed to do are "man", "no", "guy", "me", and "why".
Some require co-articulation and diphthongs. For example, "why" requires putting the tongue to the top left, /ɯ/, rounding the lips, making it /u/, then quickly releasing the lips and moving the tongue to the bottom/bottom-right, /a/, then sliding it to the top right, /i/, so that you end up with /uai/ which is pretty close to the correct English /waɪ/.
