Sympathy! I can't say btdt - I went back to our photos from that age to remind me what Colin was into at that age, and was struck by the big smile in every photo; we were lucky enough to have the kind of giftie who shows it by having an extremely long attention span and being happy to self-entertain from very young. All the same, maybe some things we did might strike a chord. Things he loved:
- his "baby nest", like this one:

It was great for the not-quite mobile age, because he could lean forwards or backwards on it, practise climbing out of it, rotate round it etc. At a later stage wearing as a hat was more fun, and keeping toys in it. This was definitely one of the baby items we got most use out of.
- playing (or "playing"!) the piano, strapped into his high chair
- his bead maze
- playing with one of those big inflatable exercise balls - being bounced on it, rolling it around, using it as a musical instrument, sitting it in his baby nest and knocking it out, etc.
- babyswim classes
I also second the recommendation to try baby sign - we did it rather half-heartedly and Colin never really caught on, but it works wonders for many babies and sounds as though it might be really useful in your case.
