It will be interesting to see if this will trigger another Scottish independence vote.
Scotland voted - with a moderate margin - to remain within the UK in 2014. However, given that the Scots are strongly in favor of EU membership, it is possible that these recent results may trigger a new referendum.
The first minister of Scotland has just hinted that this might just happen:

Sinn Fein has also called for a border poll (pertaining to a re-unification of Northern Ireland with Ireland) given that voters in Northern Ireland were also in favor of staying within the EU. I think this would be less likely than Scottish independence, though, given the historically large majority in Northern Ireland in favor of staying in the UK.
It will also be interesting (=scary) to see exactly how costly Brexit will be for the UK, as this will depend on the future trade relations between the UK and EU. The EU obviously doesn't have a lot of incentive to give the UK favorable future trade terms, as this would effectively "reward" the UK for leaving the EU.
Furthermore, the UK no longer has any leverage in negotiations with the EU (the leverage was the threat to leave, which has now become reality), so the EU really doesn't have any reasons to give any concessions on trade issues to Cameron (or his likely soon-to-be successor).
And finally, the timeframe of the negotiations will in itself create uncertainty about the UK economy, which will add to its economic woes. It may take years to reach a full agreement with the EU, and some businesses may choose to allocate their investments to other countries with a more stable access to the European market than the UK during this process.
EDIT: The following tweet by the leader of the largest party group in the European Parliament tends to confirm the above suspicions:
